Pain caused by old injuries, commonly caused by local chronic, sterile inflammation, can generally be treated with oral non-steroidal anti-inflammatory drugs, which eliminate local chronic inflammation and also have a pain-relieving effect. You can also apply local topical ointment that dispels wind, relaxes tendons and activates blood stasis. Physical therapy, such as ultrasound therapy, microwave therapy or ultrashort wave therapy, is a deeper form of physical therapy, which can reach the periosteum and the periosteum, promote blood circulation of deep inflammation, accelerate the absorption of inflammatory factors, and thus promote tissue repair. If the above treatment does not improve, you can choose local small acupuncture therapy or local closure therapy.
