Hi Doctor, I am a 40 years old women and have two kids. For the last ten years I am suffering from back pain which mostly goes to my leg. I have been trying physiotherapy, muscle strengthening exercises supported by physiotherapists, consulted Chiropractic clinics, etc. But so far the pain is till there and getting worse. Recent MRI result indicated that there is a problem on both sides of my hips( hip displacement) and recommended treatment (physiotherapy and compressor machine) for a month to fix them back and strengthen the muscles. Though there is improvement, I have a different pain on my left Thigh and Leg and it is getting worse. I can see a reddish color the side of thigh, it is not painful when I touch it but inside I feel pain and burning on thigh all the way to my leg. It gets worst when I walk. I don t know what to do and whom to consult (internist, bone specialists, etc.). and I am worried that this might not be a simple thing...I worried and not sleeping. That s why I am writing you to advise me. Awaiting for your response, Thank you so much! Email address: YYYY@YYYY

Hello, I have studied your case. As per your history there can be possibility of hip arthritis which can be degenerative or due to avascular necrosis of femoral head [AVN]. I will advise you do X-ray of hip, and you can consult me with reports or with your doctor. After clinical examination IF AVN is suspected then you will need MRI again with spine screening. Till time take analgesic and cartilage protecting medication like glucosamine sulfate. For hip arthritis joint flexion, extension and rotation exercises will help. Physiotherapist will help you better to learn more exercises in proper protocol. If required intra-articular injection can be given. Diet rich in calcium and protein will help Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
