The causes of bunion pain may include poor blood circulation, gouty arthritis and tenosynovitis. 1. Poor blood circulation: Poor blood circulation in the localized area of the toes due to squeezing of shoes and exposure to cold can cause bunion pain, which can be alleviated by applying hot compresses, massaging and soaking the feet. 2. Gouty arthritis: Most patients with gout have pain in the big toe as the first symptom, accompanied by redness and swelling of the skin as well as elevated temperature. Patients should adjust their diets and eat less purine-rich foods such as beef and mutton, animal offal, and so on. At the same time, you can follow the doctor’s instructions to take drugs such as indomethacin, diclofenac, etoricoxib and so on to relieve the symptoms. 3. Tenosynovitis: acute and chronic inflammation of the tendon sheath due to excessive activity, causing a nerve pain in the big toe. The patient should reduce the activity of the diseased part, massage appropriately, and at the same time can take the local closed to carry on the treatment. A nerve pain in the big toe should be clarified in time to determine the cause of the disease, and the symptoms continue to be unrelieved to be diagnosed and treated, so as to avoid delays in the condition.
