Patients with tenosynovitis may experience swelling. Tenosynovitis primarily results from engaging in certain activities over an extended period, causing frequent movements of the tendon within the tendon sheath, which leads to inflammatory damage, resulting in swelling, pain, and restricted movement of the tendon and tendon sheath. Treatment for tenosynovitis is mainly divided into non-surgical and surgical treatment. Non-surgical treatment involves resting, using anti-inflammatory pain relief medications to alleviate symptoms, and can also include methods like heat application, physical therapy, and local blockades, which can play a positive role in improving symptoms and reducing inflammation. Of course, if conservative treatment is ineffective, or functional impairment occurs, surgical treatment may also be considered.
