Stiffness • Toe Ache • Heel Ache • Numbness and Tingling • Swelling • Pores and skin Considerations
Because the literal basis of our our bodies, our ft are essential to retaining us energetic and wholesome. It’s straightforward to take these workhorse appendages with no consideration, however when issues come up, the ripple results make the ft exhausting to ignore.
“When one thing goes flawed in your foot, your complete physique normally has to cope with it,” says biomechanist Katy Bowman, MS, writer of Easy Steps to Foot Ache Reduction. Even a small space of soreness or irritation might be sufficient to maintain you out of your every day stroll or trigger different physique components to compensate in ways in which result in additional points.
“The common particular person takes hundreds of steps every single day, and if there’s one thing just a little bit off within the biomechanics — which means the construction or operate of the foot — it received’t simply have an effect on the foot; it’s going to have a domino impact all the best way up the physique,” notes Robert Kornfeld, DPM, a holistic podiatrist on the Persistent Foot Ache Heart in New York Metropolis. The reverse can also be true: It’s not unusual for knee, hip, and again ache to resolve after foot points are addressed.
Many people are unaware that the ft might be harbingers of systemic well being issues. “The foot is a mirror of what’s occurring in the remainder of the physique. Podiatrists are sometimes the primary ones to diagnose vascular and neurological issues, thyroid circumstances, and diabetes,” Kornfeld says.
Let’s delve into six frequent foot complaints and the systemic points they might be signaling, plus methods for addressing them.
1) Stiffness
Attainable causes: Inactivity, irritation from arthritis, constrictive sneakers
The primary contributor to stiff ft additionally results in rigid shoulders and hips — lack of standard and thorough motion. “Although the foot is small, it has a lot of hinges, and every of these hinges must be moved,” Bowman says.
Sitting for hours is surprisingly exhausting on the ft. “Inactivity, which tightens the hips and pelvis, can then tighten the ft, as a result of your ft and hips are very a lot linked,” says Emily Splichal, DPM, a functional podiatrist on the Heart for Useful and Regenerative Podiatric Drugs in Chandler, Ariz.
Systemic irritation, typically a characteristic of arthritis, additionally contributes to stiff ft. “Irritation might be regarded as stickiness — it causes a number of soft-tissue adhesions,” says Splichal. Common motion reduces stickiness and retains the joints of the decrease physique robust and versatile.
Footwear is one other necessary participant. “More often than not, our ft are wrapped in one thing very stiff that immobilizes their components,” Bowman notes. Think about sporting tight, inflexible mittens in your fingers every single day: Your wrists and forearms would compensate as you realized to make use of every hand as a single digit, dropping the muscular management and adaptability to separate them into their constituent components. That is primarily what fashionable footwear has accomplished to our ft.
“In contrast with our ft’s pure, unshod state, our sneakers are stiff, normally prop our heels above our toes, and depart no room for our toes to maneuver,” Bowman says. This results in weak, underdeveloped foot muscle tissues and places stress on the decrease leg, in addition to on the joints, fascia, and ligaments within the ft.
“Our ft, in sneakers and on flat concrete, are kind of like our digestion on a crappy eating regimen — they’re starved of the nutritious motion inputs they want for well being,” she notes.
Foot arches which might be both flat and weak or excessive and tight are additionally an indication of inflexibility. Bowman describes the arch as an motion by the muscle tissues within the ft and hips. A flat foot signifies an absence of the power wanted to create an arch, whereas excessive, rigid arches can level to extreme stress.
Both can cease the midfoot from stretching out and springing again up once more to cushion our steps. And each might be helped with workouts to construct power and adaptability within the ft. (For feet-strengthening workouts, see “Power Coaching for Your Toes.”)
2) Toe Ache
Attainable causes: Gout, bunions, ingrown toenails
If you assume “toe ache,” eating regimen won’t be the primary perpetrator that springs to thoughts. However diet-related gout, an inflammatory situation that causes swelling and ache within the joints, typically reveals up first within the foot. “It’s a crimson, scorching, infected big-toe joint the place even the blankets in your mattress are sufficient to trigger ache,” Splichal explains.
Gout can have a genetic element, however eating regimen is normally the largest contributing issue. Purple meat, seafood, sweetened drinks, and alcohol all include excessive ranges of compounds known as purines, which the physique breaks down into uric acid. These acid crystals can accumulate within the joints, resulting in ache and irritation. Dietary adjustments are the primary line of protection right here. (For extra on uric acid, see “Uric Acid: A New Metric for Coronary heart Well being.”)
However, a bunion — which seems as a bony bump on the joint on the base of the large toe — is normally a “purely biomechanical situation,” Kornfeld says. Bunions can type as a result of gait patterns, instability within the first metatarsal (the bone extending towards your ankle from the large toe), and overpronation, and they’re exacerbated by slender sneakers that pressure the large toe towards the pinky. They have an inclination to happen extra ceaselessly in girls and older individuals, presumably as a result of comparatively weaker connective tissue and the cumulative results of biomechanical dysfunction.
If the ligament holding the primary metatarsal is free or unstable (presumably from inadequate collagen, which stabilizes ligaments), it might probably trigger retrograde forces to push the bone out to type a bunion. However corrective workouts can enhance joint stability, even in individuals with a genetic tendency towards decrease collagen ranges.
And minimizing time in excessive heels, which put the physique’s weight proper over the big-toe joint, might be preventive. “Intervention is vital within the early phases of bunion formation so it doesn’t progress right into a deformity that creates issues sporting sneakers, causes ache, and limits exercise,” Kornfeld says.
Ingrown toenails, during which the borders of the nail flip downward and dig into the pores and skin, are a standard reason behind toe irritation, redness, swelling, and ache. Once more, tight sneakers might be responsible, Splichal explains. “In case your sneakers are pushing the sting of the nail into the pores and skin, that might contribute to an ingrown nail.”
Bunions could be a issue right here, too, due to how they alter the angulation of the step and push the nail into the pores and skin. And reducing toenail corners too aggressively permits the pores and skin to elevate above the nail border, so the nail grows into the pores and skin. Podiatrists suggest reducing toenails straight throughout to keep away from this.
“I’d additionally encourage a affected person to make use of toe spacers if they’ve a bunion, discover better-fitting sneakers that don’t push the nail in, and presumably put urea on the nail to melt it so it’s not so exhausting and painful,” says Splichal.
3) Heel Ache
Attainable trigger: Plantar fasciitis
Plantar fasciitis is irritation of the thick band of fascia that runs from the heel bone to the toes. It may be attributable to a one-time occasion during which you overload the tissue, comparable to strolling for miles on trip in new sneakers. Or it might probably develop over an extended interval in response to posture or mobility points within the ft, says Bowman.
“Plantar fasciitis is biomechanical in origin,” Kornfeld explains. “One typical trigger comes from the calf muscle being overly tight in compensation for hypermobility within the forefoot. The tighter the calf muscle will get, the better the pull and stress on the plantar fascia, which might injure cells and trigger them to turn out to be chronically infected.” Small tears may develop within the plantar fascia, including to ache and irritation.
The antidote, says Bowman, is mobilizing and stretching the foot. “You’ve obtained this stiff, tense wad of injured tissue, and also you wish to stretch and clean it out like a ball of dough.” She suggests utilizing focused stretches and rolling the foot out on a ball. “These are methods of waking up this tissue that’s clumped to guard itself.”
Different methods embody getting a biomechanical analysis to assist establish problematic gait and posture habits, altering your footwear, and making an attempt acupuncture.
Whereas some could profit from taping or utilizing an orthotic or brace, Bowman stresses the significance of figuring out the underlying trigger. “You wish to get your foot working higher for you with out all that gear, or else you’re probably not attending to the foundation of the issue.”

4) Numbness and Tingling
Attainable trigger: Peripheral neuropathy
When nerves within the fingers and ft are broken, peripheral neuropathy may result. Signs embody numbness, tingling, lack of stability, weak spot, or a wound on the foot that received’t heal.
Diabetes (each sort 1 and sort 2) is the commonest set off: Excessive blood-sugar ranges can injury nerves over time. Different potential causes embody vitamin B12 deficiency, bodily damage to the nerves, chemotherapy, treatment uncomfortable side effects, ingesting an excessive amount of alcohol, or viral sickness.
“I’ve fairly a number of sufferers who developed post-COVID peripheral-nerve irritation and signs,” notes Splichal. Shingles can also be identified to be a possible set off for neuropathic ache or numbness. Lupus, rheumatoid arthritis, and different autoimmune circumstances can contribute by creating irritation in peripheral nerves.
Key to reduction from all these circumstances is decreasing that inflammation. Splichal recommends an anti-inflammatory eating regimen that helps secure blood sugar, nutrient stability, and microcirculation. “All of our blood vessels have tiny branches that go to the nerves, so you want to consider microcirculation to help nerve well being,” she says.
Splichal additionally treats her neuropathy sufferers with red-light remedy. And a few individuals discover transcutaneous electrical nerve stimulation (TENS) and acupuncture useful.
5) Swelling
Attainable trigger: Fluid retention
Swollen ft and ankles could also be associated to edema, when an excessive amount of fluid turns into trapped within the physique’s tissues. Edema might be attributable to poor venous return (when the physique’s potential to pump blood up and away from the ft is compromised), consuming an excessive amount of salt, being pregnant, being premenstrual, or sitting or standing in place for too lengthy.
It might even be a aspect impact of sure medicines or an indication of insulin resistance. “Uncontrolled blood sugar creates free radicals and irritation that damages collagen within the blood vessels, in order that they begin to lose integrity,” Splichal says.
Edema can sign much more critical circumstances, together with problems with the kidneys, liver, or coronary heart. When you’ve got persistent swelling in your ft and ankles, it’s clever to examine along with your healthcare supplier.
Regardless of the underlying situation, swelling within the ft and ankles is normally relieved by elevating them. And whereas taking a stroll can typically improve swelling (particularly in scorching climate), strolling supplies a internet profit. The calves are often called the “second coronary heart” due to the position they play in pumping blood by the decrease a part of the physique.
“The ft, being farthest away from the guts, run the best danger of poor circulation; your cardiovascular system relies upon closely on the motion of the muscle tissues within the ft and decrease legs,” writes Bowman in Easy Steps to Foot Ache Reduction.
The easiest way to lend the guts a hand is to get transferring. “You want a pumping mechanism to get the blood again as much as the guts, and strolling is a good way to activate that calf pump,” Splichal explains. (For extra in your calves and cardiovascular well being, see “The Stunning Connection Between Your Calves and Coronary heart Well being.“)
6) Pores and skin Considerations
Attainable causes: Plantar warts, fungal infections, intestine dysbiosis, thyroid points
Our ft are topic to a lot of rubbing, friction, and speak to with moist environments, from the insides of our socks to the bathe flooring on the fitness center. Whereas blisters and calluses might be dealt with with just a little TLC and a change of sneakers, warts and protracted fungal infections are harder nuts to crack.
“Plantar warts are related to the human papillomavirus [HPV],” Splichal notes. Genetics and general immune standing can have an effect on how effectively somebody fights HPV. Some could develop small warts that self-resolve, whereas others find yourself in lengthy battles with warts that refuse to vanish.
“Warts like darkish, moist environments,” she says. “For those who’re retaining your ft in socks for 10 hours a day, that’s an ideal breeding atmosphere.” She suggests exposing your ft to open air as a lot as attainable to dry them out.
Splichal additionally cautions in opposition to selecting at a plantar wart, as a result of they’ll unfold to your fingers or your different foot.
For small warts, making use of a topical salicylic acid may do the trick, she notes. “However once they get bigger, you wish to go to a podiatrist or dermatologist to allow them to freeze or burn it off.”
In the meantime, dry, itchy pores and skin on the ft normally indicators fungal an infection. Fungus can infect the nails, the pores and skin between the toes, or the underside of the foot. “They’re all handled just a little bit in another way,” Splichal says.
An an infection underneath the nail may require oral medicines. “For those who simply put one thing topical on, it’s exhausting for the treatment to get by the exhausting nail to achieve it.”
Treating a fungal an infection that begins between the toes and spreads, comparable to athlete’s foot, requires retaining moisture-prone areas dry. These infections can normally be handled with antifungal lotions or sprays. Tea tree oil is a pure antifungal remedy for athlete’s foot.
Some suppliers see fungal infections on the ft as an indication of intestine dysbiosis and an extra of fungus within the GI tract. “After we handle what’s occurring at a intestine stage, now we have a significantly better alternative to eliminate it,” Kornfeld notes.
Lastly, itchy ft can sometimes sign an issue with the thyroid. “Thyroid dysfunction causes issues [with] replenishing and changing pores and skin cells,” he explains. That may lead to dry and useless cells accumulating on the floor of the pores and skin, inflicting itchiness.
Discover Your Stride
Noting that prevention is the very best treatment of all, Splichal presents these 4 suggestions for every day foot upkeep:
- Launch stress within the ft with energetic stretches or therapeutic massage.
- Activate the muscle tissues with easy workouts.
- Have interaction the foot muscle tissues and create stability with single-leg balancing for 10 seconds on all sides.
- Stimulate sensation by spending time barefoot.
Bowman reminds us that our ft deserve at the least as a lot consideration as our different physique components. “For those who do pull-ups or upper-body workouts, be sure to’re giving your ft the identical courtesy. You’re going to ask extra out of your ft than you might be out of your arms and shoulders all through your lifetime.”
Why Go Barefoot?
To develop robust muscle tissues, dense bones, and wholesome nerves, our ft should be labored identical to different physique components. That’s why some podiatrists suggest spending as a lot time as attainable barefoot — or in minimalist footwear that protects the pores and skin and permits the foot its full vary of movement.
“Tissue must really feel load so as to adapt,” explains biomechanist Katy Bowman, MS, writer of Rethink Your Place. “For those who’ve cushioned and immobilized your ft with inflexible sneakers, they now not really feel load. So, you’re placing the weakest a part of you beneath your whole physique weight.”
Nonetheless, don’t simply chuck your Chucks and head out for a barefoot dash. “There’s a number of transitional work wanted in case you’ve been sporting sneakers for many years,” she cautions. “Workouts and consciousness may help you transition efficiently.” (For extra on barefoot coaching, see “Naked Your Sole: Barefoot Coaching.”)
