Hi Thanks for your query and Welcome to Healthcare Magic. I am Dr Akshay from Fortis Hospital, New Delhi. You have mentioned that you had a knee replacement surgery around 6 weeks back and even after that you are having a lot of pain. Normally pain after a knee replacement surgery should start settling 6-8 weeks from the date of surgery and should be a bare minimum at 3 months , and there should be no pain from 6 month onwards. But some patients can have pain for a slightly prolonged periods of time. Anyways if there is only pain, but no other s/s of inflammation or infection like Skin redness, increasing swelling, local warmth etc , then it can be managed by : - Ice packs for few more days - Change in the medications you are taking , maybe a combination of Tramadol + Paracetamol can be given if it is routinely used by your Orthopaedic surgeon. - Physical therapy can be modified according to your pain tolerance as aggresive physical therapy can sometimes increase pain after knee replacement surgery. Also you can initially limit your ambulation and other activities as per your pain tolerance, or as guided by your physical therapist. As far as your spine problem goes, i can advise you in detail if i have a detailed information about your problem including neurological examination and relevant MRI images and report. Do not hesitate to contact me if you need any further assistance. Thanks & Regards Dr Akshay Kumar Saxena
