The causes of foot pain are very diverse, ranging from simple strain to vascular problems requiring emergency care. The following content is organized based on authoritative sources such as Harvard Health and People’s Daily Health.
🦶 What Types of Foot Pain Are There? What Are the Causes of Each?
Foot pain can be classified by location of pain (forefoot, midfoot, hindfoot) or by cause (soft tissue, vascular, skeletal, neurological, etc.).
1. Heel Pain (Hindfoot)
-
Plantar fasciitis: The most common cause of heel pain. The plantar fascia (the tough band of tissue extending from the calcaneus to the toes) develops micro-tears and inflammation due to long-term overload pressure. Typically presents as sharp heel pain on the first step in the morning or when standing up after prolonged sitting, which eases after a few steps but worsens again after walking for a while. Prolonged standing, walking, excessive exercise, flat feet/high arches, and improper footwear can all trigger it.
-
Achilles tendinitis: Pain at the back of the heel, caused by overuse of the Achilles tendon (which connects the calf muscles to the calcaneus).
-
Calcaneal bone spur: Bone hyperplasia on the calcaneus, often accompanying plantar fasciitis, but only about 5% of patients experience pain.
2. Plantar/Midfoot Pain
-
Flat feet/High arches: Collapse or excessive height of the arch leads to uneven force distribution in the foot, which can cause pain in the medial midfoot, extending to the ankle and medial calf.
-
Metatarsalgia: Pain and inflammation in the forefoot (metatarsal head region), often triggered by high-impact sports and ill-fitting shoes (especially high heels). Patients often describe it as “walking on stones.”
3. Toe/Forefoot Pain
-
Hallux valgus (bunion): A bony prominence at the base of the big toe, caused by long-term wearing of tight shoes (pointed shoes, high heels) leading to the big toe tilting toward the second toe. Women are at 9 times higher risk than men.
-
Morton’s neuroma: Thickening of the tissue around the nerves between the toes, causing burning, stabbing, or numbness in the forefoot, often triggered by tight shoes or high heels, and more common in women.
-
Gout: Usually located at the big toe joint, caused by the deposition of urate crystals. It can be triggered by drinking alcohol at night and worsens 8–12 hours after drinking.
-
Ingrown toenail: The toenail grows into the surrounding skin, causing throbbing pain, redness, and swelling, most commonly in the big toe.
4. Vascular/Systemic Disease-related
-
Lower extremity arteriosclerosis obliterans: Foot ischemia can cause pain and even necrosis.
-
Diabetic foot: Foot infection can cause pain. Diabetic patients have reduced foot sensation and are prone to injury without realizing it.
-
Rheumatoid arthritis, ankylosing spondylitis: Systemic diseases can also cause foot pain.
🚨 When Should You Seek Medical Attention?
If any of the following occurs, it is recommended to see an orthopedics or rehabilitation department as soon as possible:
-
Pain lasts more than 1–2 weeks and home care is ineffective
-
The heel is red, swollen, and hot, with night pain, or you cannot walk normally
-
The pain is getting worse and affects work and life
💊 Medications
Topical first: For mild pain, topical anti-inflammatory and analgesic ointments can be used first.
Oral medications (for more severe pain, short-term use under medical guidance):
-
Non-steroidal anti-inflammatory drugs (NSAIDs): Such as diclofenac sodium, loxoprofen sodium, ibuprofen, which can relieve pain caused by aseptic inflammation of soft tissues such as fascia and ligaments.
-
Blood circulation-promoting drugs: Such as Venoplant (aescin), which can relieve heel muscle pain to some extent.
-
Chinese patent medicines: Such as Huoxue Zhitong Capsules, Longxuejie Capsules, or topical Yunnan Baiyao aerosol, which may be used as appropriate.
Note: Medications should be used under medical guidance and not abused long-term.
🧘 The Best Treatment and Care Methods
Acute phase (severe pain, redness, and swelling) — first let the foot “take a break”
-
Adequate rest: Reduce standing, walking, and running/jumping. Use crutches to reduce load if necessary.
-
Correct ice application: Apply an ice bag wrapped in a towel to the painful area, 15–20 minutes each time, 3–4 times a day, to constrict blood vessels and reduce inflammation.
-
Compression and elevation: Wrap moderately with an elastic bandage, and elevate the foot above heart level when resting to promote swelling reduction.
-
⚠️ Absolutely do not soak the foot in hot water during the acute phase: Heat application will aggravate inflammation and edema, making it worse the more you soak.
Rehabilitation phase — relax the fascia and strengthen the muscles
-
Fascia ball release: Place a tennis ball, fascia ball, or mineral water bottle on the ground, step on it and roll slowly, 3–5 minutes each time, 2–3 times a day. The pressure should be sore but comfortable, and do not crush violently.
-
Stretch the posterior calf muscles: Face a wall, extend the affected leg behind with the heel on the ground, lean the body forward to feel the calf stretch, hold for 30 seconds, do 3–5 sets. A calf that is too tight will pull on the plantar fascia and worsen pain.
-
Strengthen the small muscles of the sole: Use the toes to grab a towel or beans, 10–15 times each time, to exercise the supporting strength of the sole.
Professional treatment (if there is still no improvement after 6–12 months of conservative care):
-
Shockwave therapy: Especially effective for chronic pain
-
Custom orthotic insoles: Make exclusive support pads according to foot shape
-
Ultrasound physiotherapy: Promotes absorption of inflammation
🦾 Supports and Exercise Equipment
Supports:
-
Arch support insoles/custom orthoses: Improve arch force distribution and are an important aid in the rehabilitation of plantar fasciitis.
-
Night splints: Worn during sleep to prevent contracture of the plantar fascia.
-
Heel cups/silicone pads: Wear athletic shoes with air cushions, or insert silicone heel pads, to quickly reduce pressure.
Foot massagers (such as Philips foot massagers):
-
3D airbag wrapping: Large airbags on the dorsum of the foot press downward, and ankle airbags squeeze from both sides, relieving soreness and swelling.
-
42°C constant-temperature heat: Dispels cold and warms both feet.
-
Automatic shut-off: Automatically turns off after 15 minutes for safe use.
-
Note: The heat function should not be used during the acute phase with redness and swelling.
Exercise equipment:
-
Fascia ball/tennis ball: Basic tool for plantar fascia release.
-
Stretching board (calf stretcher): Can stretch muscles and also serve as a stepping board to improve blood circulation and relieve plantar fasciitis discomfort.
-
Resistance bands: Used for stretching training of the sole and calf.
⚠️ Behaviors That Particularly Need to Be Avoided
1. Soaking the foot in hot water during the acute phase (the most common mistake)
Many people soak their feet in hot water when it hurts, but it is absolutely not recommended during the acute phase (within 48–72 hours). Hot water rapidly dilates blood vessels and increases local blood flow, increasing inflammatory exudate, making swelling more obvious and pain worse. For people with diabetes, lower extremity varicose veins, or decreased skin sensation, soaking feet in hot water can easily cause burns, ulceration, and even infection.
2. Vigorously pounding or forcefully massaging the painful point
This will further damage the fascia and make it worse.
3. Toughing it out and walking more to “exercise it open”
The more you exercise, the worse the damage. The core of plantar fasciitis is overuse + improper force distribution, and it cannot be solved by “exercising it open.”
4. Wearing flip-flops
The structure of flip-flops is not conducive to foot health. When walking, you need to curl your toes back and turn the ankle inward to grip the sole. Over time, this causes abnormal force on the tendons, foot muscles, and plantar fascia, resulting in injury and pain. Moreover, flip-flops have no arch support or heel fixation, making the arch prone to fatigue, pain, and even inflammation, and also making falls more likely. If pain occurs in the calf, sole, toes, or arch after wearing them, they should not be worn again.
5. Long-term wearing of high heels, pointed shoes, or flat thin-soled shoes
These shoes lack support and cushioning, aggravating uneven force distribution in the foot, and are important triggers for hallux valgus, metatarsalgia, and Morton’s neuroma.
6. Sudden excessive walking or a sudden increase in exercise volume
The “weekend warrior” type (not exercising normally, then suddenly walking 5 kilometers on the weekend) is most likely to injure the plantar fascia. Exercise should be progressive.
7. Walking barefoot on cobblestones (special populations)
Special populations such as diabetic patients, people with flat feet, and patients with osteoporosis should not strengthen their feet by walking barefoot on cobblestones. If the foot is in an acute pain episode, it is also not recommended to continue stimulation.
8. Ignoring “red flag” symptoms
If the heel is red, swollen, and hot, with night pain, or you cannot walk normally, or if pain lasts more than 1–2 weeks and home relief is ineffective, seek medical attention as soon as possible rather than continuing to handle it on your own.
