A, ankle sprains Causes: repeated sprains ankle joint or premature aging Ankle injury is a common ankle trauma osteoarthropathy, mostly due to playing soccer when the ankle protection is not in place, multiple sprains resulting in ankle osteophytes, may lead to long bone spurs in the joint, the damage is irreversible, and may even make the joint bones early “aging”. In many cases, cramps are a signal from the body to remind us that the body is already overloaded. When a bruise or sprain occurs, it is not recommended to use medicinal wine to apply to the injury or rub and massage it. Sports should be stopped immediately, cold compress within 24 hours of injury, can go to the nearest hospital bandage, if suspected fracture, need to be fixed, 24 hours after the hot compress. In addition, before exercise must be warmed up. Second, plantar fasciitis Causes: stepping on pebbles improper, unreasonable pedicure massage Plantar fasciitis is due to the impact of external violence on the plantar muscles or prolonged walking, causing muscle strain resulting in local inflammation of the fascia. The common symptoms are: heel pain, discomfort, pressure points often in the plantar near the heel, sometimes more intense pressure pain, and persistent. Most of the patients are elderly, many “health road” on the cobblestones are not uniform standards, some are too sharp and thin, the elderly stepped on it, the foot stimulation is too large, it will lead to the formation of bone spurs and plantar fasciitis, which is the more you step on the bottom of the more pain. Foot massage is the same reason, some people like to be masseurs vigorously stimulate the soles of the feet, and then pain also gritted teeth to endure, in fact, is not the more pain the better. It is recommended to avoid strong stimulation of the sole, the sole of the shoe should not be too thin, the heel of the shoe is best in about 3 cm, choose shoes with raised structure of the heart of the foot, the heel is soft and has a shock-absorbing effect. Third, the Achilles tendon rupture Causes: trauma The Achilles tendon rupture is mostly caused by accidental injuries, easily occurring in the more confrontational sports, such as playing badminton, basketball, etc.. The easiest way to identify an Achilles tendon rupture is to pad your toes and lift your heel, which is generally not done by people with Achilles tendon rupture. If further diagnosis is needed, be sure to go to the hospital for an MRI. Once the Achilles tendon rupture occurs, early surgery is required. Delayed treatment can easily lead to muscle tightening and spasm in the Achilles tendon area, at which time only Achilles tendon reconstruction surgery can be taken, and the prognosis will be greatly reduced. It is recommended that people who love sports should do 3~5 minutes of preparatory activities before exercise to fully warm up and avoid participating in very strong confrontational sports when they are overly tired. Patients with skeletal inflammation should pay extra attention when exercising, and it is not recommended to participate in high-intensity confrontational sports. Fourth, diabetic foot disease Causes: diabetic complications The World Health Organization defines diabetic foot disease as foot infections, ulcers and deep tissue destruction associated with local nerve abnormalities and peripheral vasculopathy in the distal lower extremities. In mild cases, foot deformity, dry and cold skin; in severe cases, ulceration and gangrene. Diabetic patients account for more than half of all non-traumatic amputations, much higher than the number of patients who have to have their feet amputated due to trauma. Ischemic diabetic foot ulcers are currently the number one cause of nontraumatic amputations. Patients with diabetic foot disease, foot washing, toenail clipping, buy shoes must pay attention to, foot washing time should not be too long, should be controlled at about 15 minutes, the water temperature should not be too high, do not exceed 37 ℃, to avoid burns; after washing feet dry toe seam, avoid moisture. Diabetic feet are prone to calluses and dry foot skin, care can be softened with some softening oil to soften the keratin. Be careful when pedicure, once there is a breach is easy to infect. In addition, it is recommended to use special shoes, insoles and diabetic socks for diabetes. The correct self-treatment after an ankle injury is essential for the recovery of the ankle joint. Nowadays, the common measure is “PRICE”. 1.Protection：After the injury, you should do a good job of local protection and stop exercising to avoid secondary injury. 2, rest (Rest): dynamic rest, other parts can be active. 3, cold compress (Ice): the purpose is to make microvascular contraction, reduce bleeding, prevent lymphatic swelling, reduce the local metabolic rate, reduce muscle spasm and other phenomena. Cold compress method: once every hour, 10 to 15 minutes each time (about until the numbness disappears), pay attention to prevent frostbite (add water, wet cloth, adhesive film, etc. so that the skin contact temperature can not be lower than 0 degrees Celsius), while avoiding superficial nerves (peroneal nerve of the ankle). 4.Compression: It can help to reduce swelling and bleeding effectively. 5. Elevation of the affected limb (Elevation): also to reduce swelling and slow down the amount of bleeding and tissue fluid exudation.
