The symptoms of tenosynovitis mainly manifest as pain, swelling, and limited mobility in the affected area. Tenosynovitis is primarily a condition caused by long-term engagement in certain activities, leading to frequent movement of the tendon within the tendon sheath, which results in inflammatory damage to the sheath. When a patient with tenosynovitis is asymptomatic, treatment may not be necessary, and rest is typically sufficient. However, when symptoms do appear, treatment becomes necessary. Initial measures include rest and the symptomatic use of anti-inflammatory and analgesic medications, as well as medications that invigorate the blood and dispel stasis. Treatment can also be supplemented with methods such as heat application, physical therapy, and local injections to help improve symptoms and achieve favorable outcomes. When mobility impairments occur, surgical treatment may also be needed.
