Tendinitis is not usually cured by taking medication, the disease itself has a tendency to heal itself, but taking medication can relieve the symptoms and shorten the course of the disease. Because the disease is inflammation, but this inflammation is aseptic inflammation, so take anti-inflammatory drugs are not particularly effective. Is it possible to take painkillers for pain with this disease? Yes, temporary pain relief is possible, but if you want to treat the disease completely by taking medication, the effect is not particularly good. There is no gold standard for laboratory tests for tenosynovitis, such as taking blood to see if there are elevated white blood cells, which cannot be detected, nor can ultrasound. It is mainly based on the symptoms and signs presented, through the doctor’s judgment.
