The need to take anti-inflammatory drugs for tendonitis depends on the specific condition of the tendon sheath. If the pain is simply felt during the activity, you can not take anti-inflammatory drugs, keep the tendinitis position relaxed, rest, avoid continued activity, and pay attention to keep warm, not to appear cold, not to use cold water to wash hands or clothes, etc.. If the symptoms of tendinitis pain are heavy, you can take oral anti-inflammatory and analgesic drugs, such as diclofenac sodium enteric capsules, clonoxicam, which can effectively reduce local inflammatory stimulation, reduce inflammatory edema, relieve pain and unfavorable symptoms of activity. In case of stenosing tenosynovitis, which means that the tendon sheath has obvious edema as well as adhesions and scarring, which produce pressure on the tendon, you cannot simply take anti-inflammatory drugs, but need to go to the hospital for surgical treatment, which can take the form of local anesthesia to cut open the tendon sheath a little, or apply small needle knife for local release, in order to fully restore the normal function of the tendon.
