Plantar fasciitis and carpal tunnel syndrome are two of the most common overuse conditions doctors see, one in the heel and the other in the wrist. Both develop gradually from repeated strain, are often worse first thing in the morning or at night, and usually improve without surgery when treated early.
This article explains what each condition is, who gets it, how it is diagnosed and treated, and when to see a doctor.
Plantar Fasciitis
Plantar fasciitis is the most common cause of heel pain in adults. It affects the plantar fascia, a thick band of tissue that runs along the sole from the heel bone to the base of the toes and supports the arch of the foot.
The name suggests inflammation, but in long-standing cases, the tissue shows degeneration and micro-tears rather than active inflammation. For this reason, some specialists prefer the term plantar fasciopathy.
Causes and Risk Factors
Repeated stretching and loading of the fascia cause small tears where it attaches to the heel. Common risk factors include:
Age between 40 and 60.
Excess body weight.
Long hours of standing or walking on hard floors (teachers, factory workers, traffic police, and shop staff).
Running, especially a sudden increase in distance or speed.
Tight calf muscles or a tight Achilles tendon.
Flat feet, high arches, or an abnormal walking pattern.
Worn-out or unsupportive footwear, and walking barefoot on hard surfaces.
A heel spur seen on an X-ray is common in people with plantar fasciitis, but the spur itself is usually not the cause of pain. Many people have spurs without any symptoms.
Symptoms
Stabbing pain at the bottom of the heel, usually on the inner side.
Pain that is worst with the first steps after waking up or after sitting for a long time.
Pain that eases after a few minutes of walking, then returns after prolonged standing or activity.
Tenderness when pressing the inner heel.
Pain is usually felt after exercise rather than during it. One foot is typically affected, although both can be.
Diagnosis
Diagnosis is clinical. A doctor takes a history and examines the foot, checking for tenderness at the heel, tight calf muscles, and the foot's arch. Imaging is not needed in most cases.
An X-ray, ultrasound, or MRI may be advised if the pain does not improve with treatment or to rule out other causes, such as a stress fracture, nerve entrapment (tarsal tunnel syndrome), arthritis, or a heel fat-pad problem.
Treatment
About 80 to 90 percent of patients improve with conservative treatment, although full recovery can take 6 to 12 months.
Relative rest: Cut down on activities that load the heel, such as running and prolonged standing. Switch to cycling or swimming for fitness.
Stretching: Daily calf and plantar fascia stretches are the most useful single measure. Stretching the fascia before taking the first steps in the morning helps reduce early pain.
Footwear: Wear cushioned shoes with good arch support. Avoid flat sandals, worn-out shoes, and walking barefoot on hard floors.
Insoles and heel cups: Over-the-counter arch supports or silicone heel cups help many patients. Custom orthotics are an option if these fail.
Ice and pain relief: Rolling the foot over a frozen water bottle for 10 to 15 minutes and taking short courses of anti-inflammatory painkillers can ease symptoms.
Night splints: These keep the foot flexed overnight and reduce morning pain.
Weight reduction: Where relevant, this lowers the load on the fascia.
If pain persists beyond a few months, a doctor may consider:
Corticosteroid injection: Provides short-term relief, but repeated injections carry a risk of fascia rupture and heel fat-pad thinning.
Extracorporeal shockwave therapy (ESWT): Useful for chronic cases.
Platelet-rich plasma (PRP) injection: Evidence is still developing.
Surgery: Partial release of the plantar fascia, reserved for the small number of patients who do not improve after 6 to 12 months of proper conservative care.
When to See a Doctor
See a doctor if heel pain lasts more than a few weeks despite rest and better footwear. Seek prompt care for pain after an injury, swelling or redness, fever, numbness or tingling in the foot, or pain at night or at rest. People with diabetes should have any foot pain checked early.
Carpal Tunnel Syndrome
Carpal tunnel syndrome is the most common nerve entrapment condition in the body. It occurs when the median nerve is squeezed as it passes through the carpal tunnel, a narrow passage on the palm side of the wrist formed by the wrist bones and a tough ligament called the transverse carpal ligament.
The median nerve provides sensation to the thumb, index finger, middle finger, and half of the ring finger. It also controls some of the small muscles at the base of the thumb. Anything that crowds the tunnel, such as swollen tendons or fluid retention, raises pressure on the nerve.
Causes and Risk Factors
Female sex: Women are affected about three times as often as men.
Age between 40 and 60.
Pregnancy: Fluid retention can contribute to the condition; symptoms often settle after delivery.
Medical conditions: Diabetes, hypothyroidism, and rheumatoid arthritis.
Obesity.
Repetitive, forceful hand and wrist work: Including the use of vibrating tools in construction, tailoring, assembly-line work, and agricultural work.
Previous wrist fracture or injury.
Kidney failure and long-term dialysis.
Keyboard and mouse use has not been clearly proven to cause carpal tunnel syndrome, although awkward wrist positions can aggravate existing symptoms.
Symptoms
Numbness, tingling, or a pins-and-needles feeling in the thumb, index finger, middle finger, and part of the ring finger; the little finger is spared.
Symptoms that wake the patient at night, often relieved by shaking or flicking the hand.
Tingling while holding a phone, newspaper, or steering wheel.
Pain that may spread up the forearm.
In later stages, weak grip, dropping objects, difficulty with fine tasks such as buttoning a shirt, and visible wasting of the muscles at the base of the thumb.
Diagnosis
Diagnosis begins with a history and examination. Two bedside tests are commonly used:
Tinel's sign: Tapping over the median nerve at the wrist produces tingling in the fingers.
Phalen's test: Holding the wrists fully bent for about 60 seconds brings on the symptoms.
Nerve conduction studies and electromyography (EMG) confirm the diagnosis, measure its severity, and help rule out other conditions, such as a pinched nerve in the neck (cervical radiculopathy). Ultrasound of the wrist is increasingly used as well. Blood tests for diabetes and thyroid function may also be advised.
Treatment
Treatment depends on severity. Mild to moderate cases often respond to non-surgical care:
Wrist splint: A splint that keeps the wrist straight, worn at night, is the first-line treatment.
Activity changes: Reduce repetitive gripping and forceful wrist bending, take regular breaks, and keep the wrist in a neutral position while working.
Treating the underlying cause: Controlling diabetes or thyroid disease and losing weight where relevant.
Corticosteroid injection: An injection into the carpal tunnel provides relief for weeks to months and can help confirm the diagnosis.
Hand therapy: Nerve and tendon gliding exercises may help some patients.
Oral anti-inflammatory painkillers and diuretics have little proven benefit for carpal tunnel syndrome itself.
Surgery (carpal tunnel release) is advised when symptoms are severe or constant, when there is muscle weakness or wasting, when nerve tests show significant damage, or when conservative treatment has failed. The surgeon cuts the transverse carpal ligament to relieve pressure on the nerve through an open or endoscopic approach.
It is a day-care procedure, usually performed under local anaesthesia, with a high success rate. Night symptoms often improve within days, while grip strength may take several months to recover.
When to See a Doctor
See a doctor if tingling or numbness in the hand is frequent, disturbs sleep, or lasts more than a few weeks. Seek care early if there is weakness, clumsiness, or wasting at the base of the thumb, because long-standing compression can cause permanent nerve damage.
Sudden numbness or weakness in one hand, especially when accompanied by facial drooping or speech difficulty, requires emergency care to rule out a stroke.
Prevention
Neither condition can always be prevented, but reducing repeated strain lowers the risk and the chance of recurrence.
Preventing Plantar Fasciitis
Wear supportive, cushioned footwear and replace running shoes regularly. Stretch the calves daily, increase running distance gradually, and avoid standing barefoot on hard floors for long periods. Maintaining a healthy weight reduces the load on the heel.
Preventing Carpal Tunnel Syndrome
Keep the wrists straight while working, use a lighter grip, and take short breaks from repetitive tasks. Keep the hands warm when working in cold conditions. Good control of diabetes and thyroid disease also lowers the risk.
