One year back, I had problems 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 the X-ray, he found that the pain was due to cartilage damage in the knee. I continued the full course of medicine and after that, there was no problem in my knee. I have attached that x-ray report and doctor's prescription here for your reference. If I walk a long distance then the problem starts again and it gets cured as soon as I apply that gel. However, last week again the problem started. This time I am using a 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 a permanent cure of this knee problem? Can I walk a long distance? What precautions should be taken for knee pain? I am looking forward to your positive reply. Thank you.
