Hello,I am a 53 year old woman and have been experiencing pain in the back and inside of my right knee for about 2 weeks now. I tore my meniscus (MRI proven) about 10 years ago in a slip and fall accident in a grocery store, but the tear was minor and I did not have surgery. Have not had any problems with it as a result, just occasional slight pain. I am very active; I exercise every day alternating with various activities such as spinning, step aerobics with squats, elliptical runner and power walking. When I squat down, I feel pain and a tightness underneath my right knee and now it has extended to the inside of the knee. I feel it is probably related to the previous meniscal tear and after years of constant exercise it is wearing out??? What are your thoughts on this?
