Plantar fasciitis

Plantar fasciitis is a common cause of heel pain that occurs due to collagen degeneration and inflammation in the tendons of the foot. Plantar fasciitis can interfere with daily activities such as walking and exercise, and, symptoms can become chronic and result in pain in other body ...

Morton neuroma

Morton neuroma, also called by the older name Morton's neuroma, is a thickening of fibrous tissue in the ball of the foot. This tissue encapsulates the nerve leading to the third and fourth toes. It is not actually a tumor of the nerve, as the name suggests.

The thickening is caused by years of trauma, irritation, and/or compression to the feet. High-heeled shoes, especially if narrow or tight, are a common cause. The condition is most often seen in women over age 45.

Symptoms include burning pain in the ball of the foot, especially with walking or running. The condition will not heal on its own and can lead to chronic foot pain.

Diagnosis is made through physical examination of the foot with simple range of motion exercises, and sometimes x-ray.

Treatment includes changing to better-fitting shoes that do not compress the nerve; using orthotics in the shoes to take more pressure off of the nerve; and in some cases the use of corticosteroid injections.

Posterior tibialis tendinopathy

The posterior tibialis tendon attaches the calf muscle to the bones on the underside of the foot. It provides stability and arch support. If this tendon is damaged, the result may be a flat, unstable foot.

Posterior tibialis tendinopathy is most often a sports injury, where the tendon becomes inflamed or torn through overuse or high impact.

Symptoms include pain down the ankle and into the foot, sometimes with swelling. The pain becomes worse with any activity, even standing or walking. When standing, the patient's arch will be collapsed and flat and the front of the foot will point outward. The patient will be unable to stand on the injured foot and raise the heel.

Diagnosis is made through patient history, physical examination, and imaging such as x-ray, CT scan, or MRI.

Treatment involves rest, over-the-counter pain relievers, orthotics (shoe pads,) braces, and sometimes steroid injections into the damaged tendon. Surgery can be tried, but tends to be complex and cannot always restore the tendon completely.

Rarity: Ultra rare

Top Symptoms: swollen foot, pain in one foot, limping, pain in one ankle, spontaneous ankle pain

Symptoms that never occur with posterior tibialis tendinopathy: recent cutting accident

Urgency: Primary care doctor

Fibromyalgia

Fibromyalgia is a set of chronic symptoms that include ongoing fatigue, diffuse tenderness to touch, musculoskeletal pain, and usually some degree of depression.

The cause is not known. When fibromyalgia appears, it is usually after a stressful physical or emotional event such as an automobile accident or a divorce. It may include a genetic component where the person experiences normal sensation as pain.

Almost 90% of fibromyalgia sufferers are women. Anyone with rheumatic disease, such as rheumatoid arthritis or lupus, may be more prone to fibromyalgia.

Poor sleep is often a symptom, along with foggy thinking, headaches, painful menstrual periods, and increased sensitivity to heat, cold, bright lights, and loud noises.

There is no standard test for fibromyalgia. The diagnosis is usually made when the above symptoms go on for three months or more with no apparent cause.

Fibromyalgia does not go away on its own but does not get worse, either.

Rarity: Common

Top Symptoms: fatigue, arthralgias or myalgias, anxiety, depressed mood, headache

Symptoms that always occur with fibromyalgia: arthralgias or myalgias
