Tendinitis refers to a sterile inflammation of the tendon sheath around the tendons, caused by chronic strain, characterized by local pain and limited mobility. If tendinitis occurs, it is recommended to seek medical attention at the orthopedics department of a formal hospital. After assessing the extent of the inflammation and its impact on movement, and determining the presence of symptoms of constrictive tendinitis, an appropriate treatment method can be selected. In the early stages, conservative treatment such as rest and topical non-steroidal anti-inflammatory pain medications can be used. If the symptoms are severe, surgery may be required to remove the narrowed tendon sheath or the inflamed sterile tendon sheath to alleviate symptoms.
