Methods to improve arthritis include medication such as non-steroidal anti-inflammatory drugs (NSAIDs), surgical treatment such as arthrocentesis, and physical therapy such as infrared light therapy. 1. Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) such as etoricoxib, indomethacin, diclofenac, etc., or cartilage protectors such as glucosamine sulfate and D-glucosamine can alleviate the symptoms of joint pain. However, if the disease needs to be controlled for a long period of time, it is necessary to clarify the specific type of the disease, and then target the treatment with anti-rheumatic drugs, adrenocorticotropic hormones, antibiotics, and other medications. 2. Surgical treatment: for different types of arthritis, surgical treatments such as arthrocentesis, synovectomy, joint fusion and joint replacement can be chosen. 3. Physical therapy: ultrasound therapy, infrared therapy, ultraviolet therapy and other physical therapy modalities can help relieve the symptoms of arthritis, and should be chosen according to the specific conditions of the patient. All of the above drugs should be used under the guidance of a doctor. It is recommended that patients with arthritis go to orthopedics, rheumatology and immunology departments of regular hospitals and follow the doctor’s instructions for appropriate treatment.
