Burning sensation on the sole of the foot

Introduction When the plantar fascia is acutely inflamed, there will be a burning sensation in the soles of the feet and redness. Plantar fasciitis is a painful symptom of the sole of the foot. It is located at the heel of the sole of the foot and is a common form of foot pain.

Cause

The exact cause of the cause and pathology is still unclear and may be as follows:

(1) When walking, the metatarsophalangeal joint stretches back and pulls the plantar fascia, thereby pulling the calcaneal nodules. With the increase of age, the strength of the foot muscles and ligaments is weakened, and the strength of the plantar fascia pulling the calcaneus nodules is increased. The long-term repeated pulling causes the tiny tears at the starting point of the plantar fascia, secondary inflammation, causing pain.

(2) Fractures of periostitis at the calcaneus of the plantar fascia and the medial nodules of the calcaneus.

(3) Inflammation and edema of the flexor short muscles and its hyperplastic bone spurs cause the compression of the first nerve of the lateral plantar nerve.

Some other diseases of the foot, such as arch reduction, patella varus, heel contracture, calcaneus valgus, pre-rotation deformity, foot tendon in the middle-aged and elderly, and changes in the arch of the ligament after degeneration The plantar fascia is subjected to greater stress, and long-term chronic traction can cause slight tearing of the local aponeurosis, and local edema produces aseptic inflammation. Recently, some people have called plantar fasciitis "tennis."

Definition of plantar fasciitis Aseptic inflammation occurs in the plantar tendon, which is a type of heel pain.

Clinical manifestations: Pain in the sole of the foot near the center of the heel or the foot, usually slow onset. Occurs in more obese middle-aged women and those who love sports, such as professional athletes, dancers who walk for a long time, and ordinary people who walk long distances. In addition, people who like to wear soft-soled shoes and large amount of exercise are also common. When you get out of bed in the morning or walk the first few steps, the pain is heavier. After further activities, the pain can be partially relieved, but after a long period of activity, the symptoms can be aggravated.

The anterior medial swelling of the heel was seen during the examination. There was significant tenderness at 2-3 cm from the medial nodule of the calcaneus and the aponeurosis. Also observe whether there is abnormality of the foot line, whether there is patella varus, foot inversion and flat foot, high arch foot, and whether or not the Achilles tendon contracture. X-ray examination: About 50% of patients have spurs on the temporal side of the calcaneal nodule. B-ultrasound and MRI examination showed thickening of the aponeurosis and edema. Some people also show pain in the forefoot and midfoot.

Differential diagnosis

Plantar fasciitis needs to be identified as follows.

Plantar fasciitis can be divided into acute and chronic. In acute inflammation, there will be redness and swelling, burning sensation, local tenderness is more significant, mostly at the beginning and ending point of the lesion. After an acute attack, the symptoms of a few patients can be resolved, and most of them will leave pain. Attack again after months or years. Chronic patients often experience increased pain when the weather changes, such as rainy days, or when it is wet and cold.
