Hello Dear. For temporary pain relief you can give your husband over the counter drugs like paracetamol or ibuprofen or diclofenac. You can also apply diclofenac get at his hip joint and give warm water heat at the area. Regular exercise is important for RA. Exercise strengthens muscles that support joints. Exercise also helps to stay flexible. This is important to prevent painful falls. Physical therapy can help you learn ways to move without pain or injury. Occupational therapy is helpful to learn easier ways to perform activities of daily living, such as dressing, cooking, eating, or cleaning. Hip surgery is an option when severe pain or joint destruction causes immobility. For patients with earlier stage RA of the hip, hip arthroscopy may help to ease pain. Arthroscopy is done with a thin tube connected to a light source through a small surgical incision. The procedure is rarely performed and considered to be of limited usefulness. For more severe disease, total joint replacement may be recommended. It s estimated that about 80% of patients will have good results for 12-15 years after hip replacement. Most patients have little pain after this surgery. Hope i have answered your question. Feel free to contact me if you have any more questions. I ll be glad to help you. All the best With warm regards Dr Sanjay Kini
