Hello. About a year ago I had extreme pain in my left knee. I was unable to walk on it. Even slight pressure from my toes caused pain. I iced it and elevated it. I also took some ibuprofen. It was fine. It hurt occasionally so i elevated and took ibuprofen. Now I have times where it gets tight and I m unable to put all my weight on it. I never heard any popping noises or did and strenuous activity prior to the pain. What could be the cause?
cannot say in your particular case because there are so very many parts of the knee that could be causing it. The tendons, the cartilage often break. An MRI would be the test. Treatment .... is not great...
