A few years ago I had a meniscus repair in my left knee because I had torn my meniscus due to a discoid meniscus. Every now and again I get severe pain in my knee either randomly or associated with overuse and it can last anywhere from a few hours to a few days. It becomes very hard to move my leg from one position to another let alone walk. It reminds of the pain I experienced right after surgery once the anesthesia wore off and its not like what I felt before the surgery when I had the torn meniscus. Its been progressively getting more painful, more frequent, and lasting longer so I just want to know why my knee is still bothering me years down the line.
