Tendonitis is a common cause of wrist pain. Like many orthopedic issues, nonsurgical treatments are tried first.
Resting the wrist and wearing a brace can help prevent the tendon from contributing to more inflammation in the wrist area due to friction.
Icing your wrist can reduce inflammation, as can over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs).
If the brace and medicine don't help steroid injections into your wrist are an option.
If nonsurgical methods don't work, surgery is available.
