Achalasia is a pain syndrome in the heel caused by a series of diseases, i.e. pain on the metatarsal side of the heel (i.e. the plantar side of the foot), mostly seen in obese people after middle age and in severe cases unable to walk. The most common causes are metatarsal tenosynovitis, heel fat pad inflammation and heel spur, heel bursitis, etc. In addition, some diseases of the whole body can also cause pain in the heel. There are many patients with heel pain, especially in the elderly, because the fat pad of the elderly foot has atrophied and has to bear a lot of force with each step, which makes it easy for fat pad inflammation to occur. In addition, the muscles and ligaments of the feet of the elderly have laxity, and when the muscles and ligaments are relaxed, the feet become flat, and the plantar tendon membrane on the bottom of the foot has to withstand greater force, and due to long-term stimulation, it can also become inflamed, i.e., metatarsal tendonitis, which manifests as pain on the metatarsal side of the heel bone. Usually the onset is slow, the pain is heavier in the morning when you take the first few steps, after repeated periods of activity the pain can be partially relieved, but prolonged activity can aggravate the symptoms. Many middle-aged and elderly people have bone spurs in the heel, not everyone has pain, and it is not a common cause of heel pain disorder. The formation of heel spurs is due to the long-term contraction and stimulation of the muscles attached to the underside of the heel bone, causing local bone growth. It is often a manifestation of an inflammatory response due to strain on the metatarsal tendon membrane. Even if the pain is caused by a bone spur, the degree of pain is not proportional to the size of the spur. Only a minority of people have heel pain that disappears after removal of the bone spur, and most people still have heel pain. Treatment Most patients who have heel pain can have their symptoms relieved by non-surgical treatment. First of all, they should wear shoes with loose heels to protect their feet from great impact, and they can also be treated with physical therapy, non-steroidal anti-inflammatory and pain-relieving drugs, foot pads, traction exercises for the metatarsal tendon membrane and Achilles tendon, night-time brace immobilization, and hormonal closure therapy. Extracorporeal shock wave is a new treatment method with an efficiency of 70%-80%, and some patients can have pain relief on their own even without treatment. In a very small number of patients, symptoms may persist despite various non-surgical treatments, and sometimes surgery is required to partially sever the metatarsal tendon membrane. Exercise methods for achalasia 1. Exercise methods for heel pull: hand on the wall, one leg in front and one leg behind, do not lift the heel. One leg bow, one leg taut, alternately do, the body forward. 2, the heel on the root of the wall to come to the top of the foot. 3, standing on the steps, hand on the handrail of the stairs, the front foot stands on the steps, the heel down.
