Proxym 300 and Etova 400?mg both contain etodolac, but the strength is different, so switching on your own is not advisable. Consult your doctor, who can determine the safest and most effective option for your mother's rheumatoid arthritis based on her condition and overall treatment plan.

Etova 400?mg (etodolac) is a pain-relief medicine which should be used only as prescribed by a doctor. Since you have severe knee pain, it is best to consult a doctor who will decide the right dose and duration. Meanwhile, resting the knee, applying ice or heat, and using supportive aids can help reduce pain.

If your ankle pain and swelling have lasted 10 years and are not controlled with Etova 400?mg twice daily, it is a sign that pain medicine alone is not enough. Long-term issues may be due to arthritis, joint damage, or other underlying problems, so you should see an orthopaedic doctor. They can suggest proper evaluation, imaging, and treatment options like physical therapy, supportive braces, or other medications to manage pain and improve mobility safely.

If your mother's osteoarthritis pain and swelling are not relieved by current medicines, it is important to see her doctor or a rheumatologist for a review. They may suggest stronger or different pain-relief medicines, physical therapy, or supportive footwear. Managing weight, gentle exercises, and proper foot support can also reduce pain and improve mobility.
