When patients with tendinitis experience pain, they should first rest and avoid strenuous activities. They can also use non-steroidal anti-inflammatory drugs to relieve pain. These drugs include ointments that can be applied to the affected area, as well as oral medications that can be taken after meals for a short period to reduce inflammation and alleviate pain. Additionally, patients can use treatments such as heat application, physical therapy, and local injections, which can also effectively relieve pain. When conservative treatments are ineffective or if there is a functional impairment due to adhesions of the tendon and surrounding tissues, surgical treatment can be considered.
