Bone spur is easy to occur in middle-aged and elderly people. It is a kind of hyperosteogeny that can protrude outward at the edge of the joint or the bone of the weight bearing part due to the strain and degeneration of the joint or the bone of the weight bearing part. Usually, the bone spur can be observed regularly when there is no symptom. If there is pain or dysfunction, you need to go to the hospital for X-ray examination. At present, the medical treatment of bone spur can be divided into oral medicine and external application medicine. Oral medicine is pain relieving medicine, such as non carrier anti-inflammatory drugs and analgesics, such as ibuprofen, indomethacin, etc., and external application medicine is a traditional Chinese medicine plaster, such as Yunnan Baiyao Plaster, which can promote blood circulation, remove blood stasis, diminish swelling and relieve pain. At the same time, it can combine physical therapy to alleviate symptoms. During the medication period, you must take the medicine according to the doctor's advice, and the quantity should be fixed regularly. Do not cut down the dosage or stop the medicine at will, otherwise serious consequences will result. When the bone spur is very serious, it needs to be treated by surgery.
