How to Treat Tenosynovitis-Related Wrist Pain
The tendon sheath is a double-layered, tubular, closed synovial membrane that envelops tendons—functioning as a protective synovial sheath. It consists of two layers encasing the tendon: an inner layer tightly adherent to the tendon surface and an outer layer lining the fibrous tendon sheath. These two layers form a potential space—the synovial cavity—filled with synovial fluid. Together, the layers anchor to the underlying bone surface, serving to stabilize, protect, and lubricate the tendon, thereby minimizing friction or compression. So, how is wrist pain caused by tenosynovitis treated? The following addresses this question.

How Is Wrist Pain Caused by Tenosynovitis Treated?
Wrist pain due to tenosynovitis can be managed through oral medication or local corticosteroid injection therapy; the optimal treatment approach should be selected based on individual clinical presentation.
Chronic overuse injury is the primary cause of tenosynovitis. Common precipitating factors include repetitive, forceful movements of the fingers and wrist joints—such as those experienced by搬运 workers, frequent typists, or musicians. In early-stage disease, patients typically experience dull, aching pain at the base of the fingers, especially noticeable upon waking in the morning; mild activity often provides temporary relief. A minority of patients may notice a “triggering” or “snapping” sensation during finger flexion. In severe cases, active finger flexion or extension may become significantly restricted or impossible.
For mild symptoms, oral nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac sodium sustained-release capsules may be prescribed. Alternatively, topical application of diclofenac diethylamine gel to the painful area can help alleviate discomfort. Patients who fail to respond adequately to pharmacotherapy may benefit from local infiltration with lidocaine injection for short-term symptomatic relief.
Daily precautions include maintaining hand warmth and using warm (not cold) water for handwashing.
