question: Hi doctor, One year back, I had problem in my right knee like loose feeling, instability, slight pain, etc. When I consulted a doctor, he suggested Cartigen-Duo, Miol-OD and Acepark gel. In x-ray he found that the pain was due to cartilage damage in knee. I continued full course of medicine and after that there was no problem in knee. I have attached that x-ray report and doctor prescription here for your reference. If I walk long distance then problem starts again and it gets cure as soon as I apply that gel. However, since last week again the problem started. This time I am using kneecap for support while walking. What is the exact problem with my right knee? Should I start Cartigen-Duo and Miol-OD again? Please suggest any alternative gel as the earlier one is not available. What should be done for permanent cure of this knee problem? Can I walk long distance? What precautions should be taken for knee pain? I am looking forward for your positive reply. Thank you.
