The treatment is to inject local anesthetic drugs and long-acting glucocorticoids into the local painful spot, which can achieve rapid pain relief, anti-inflammation and swelling. The duration for which the effect of occlusion therapy can be maintained depends on the patient’s condition.

Avoid getting wet within 3 days after the closure treatment, after the closure treatment appears local redness, swelling, pain aggravation, etc., should be promptly examined and treated.
