Tendinitis refers to the inflammation of the tendon sheath around the tendon due to repeated motion and strain, resulting in symptoms such as pain and limited mobility. In the early stages, the inflammation is relatively mild and conservative treatments can be chosen, such as the topical application of non-steroidal anti-inflammatory and analgesic medications to alleviate local pain and reduce inflammation. Physical therapy can also be used to promote healing of the injury. If the symptoms are severe and there is a snapping symptom, medication alone may not resolve the condition, and surgical treatment may be necessary.
