Rheumatoid arthritis is a long-term condition where joint inflammation needs proper control, and pain relief medicines like Pirox only help reduce pain but do not control the disease itself. If she is having severe pain in multiple joints, it may mean the condition is not fully controlled. She may need specific medicines that slow the disease and protect the joints, along with regular follow-up. It would be better to review her treatment plan so the right medicines can be added to prevent further damage and improve her comfort.

Both of your mother's knees may suffer from severe osteoarthritis, which causes the knee joints to become uncomfortable and worn out. In addition to surgery, therapeutic options include weight management, mild physical therapy, knee-strengthening exercises, hot compresses, walking assistance such as a stick or knee brace, and prescription painkillers. An orthopaedic expert may also offer knee injections or calcium/vitamin D supplements for some patients. Steer clear of excessive stair climbing, floor sitting, and knee strain. She should see an orthopaedic physician to determine the severity of her arthritis and to discuss the best course of action because she is having trouble walking.
