There are many reasons for heel pain, but most of them are caused by calcaneal spur, which mostly occurs in obese people over 40 years old. There is a layer of elastic fat pad outside the periderm of human heel, which plays a buffering role when the foot bears the whole body weight, so that the calcaneus does not directly touch the ground. With the increase of age, this kind of cushion will undergo degenerative changes and lose its elastic function. The increase in weight will increase the load on both feet and the pressure on the soles of the feet. After a long time, it will lead to pathological changes and form bone spurs. When the heel slightly touches the ground, the bone spur stimulates the peripheral nerves of the surrounding tissues, and the patient feels pain. What is heel achilles tendon pain? 1. When running, the gastrocnemius of the foot contracts and lifts the achilles tendon, and the first half of the foot touches the ground. The achilles tendon is subjected to repeated violent impacts, especially when athletes have to "limit" every day, which will cause inflammatory reaction for a long time, thus leading to achilles tendon inflammation. 2, the heel is too soft, the achilles tendon is unstable in the shoe, and excessive movement of the achilles tendon will lead to instability and overload of the achilles tendon; The sole is too hard to bend the first metatarsophalangeal joint between the toe and the sole; The shoes are too big, and when you jump, you will bend your toes and dig hard at the soles. These may increase the traction of achilles tendon. 3. Sometimes athletes' actions in training are incorrect. For example, when hitting the ball online, the toes are excessively rotated internally or externally, and the ankle joint is unstable when landing, which is prone to achilles tendinitis. In addition, due to long-term and overloaded training, many officers and men will feel "foot pain", which is also a disaster caused by tendinitis. 4. Trauma and infection When trauma and infection occur near the achilles tendon, it may also lead to inflammation of the achilles tendon, so people should also protect the achilles tendon and avoid trauma. 5, flat feet For patients with flat feet, the pressure on the achilles tendon during exercise is greater than that of normal people, so the injury will be more serious, and long-term chronic injury can easily lead to achilles tendon inflammation. Nursing care of patients with tendinitis. Wash your feet with warm water every day to maintain blood circulation and reduce local inflammation. 2, cold and warm. Pay special attention to keep your feet warm in winter to avoid cold stimulation. 3, Chinese medicine preparation {Achilles tendon; Bones; Party; Shiyitie can relax muscles and tendons, promote blood circulation, relieve swelling and pain, dissipate blood stasis and dispel cold, and effectively eliminate aseptic inflammation. It is an ideal drug for the treatment of achilles tendinitis. . 4. When walking or standing for a long time, you should have a scientific gait and posture to avoid the continuous load on your feet and prevent your feet from being overtired. 5. Choose appropriate sports, such as walking, swimming and playing Tai Ji Chuan. It can promote the metabolism of the body, increase the toughness of bones and increase the growth of bones. People with mobility disabilities can do foot muscle contraction every day to enhance the muscle strength of plantar muscles and slow down the process of ligament degeneration and relaxation. 6, high-calcium diet, such as shrimp skin, kelp, seaweed, crispy fish, seaweed, sesame sauce and so on. Foods rich in vitamin C, such as animal bone soup rich in calcium, fresh vegetables and fruits, and drink more milk and soybean milk. 100 g of bean curd residue contains calcium 100 mg, which is almost equal to the calcium content of milk. It is the cheapest and most accessible calcium supplement.
