Could be you knee or: If you have a history of back pain, even at your young age it could be sciatica! However, assuming that's not the case, then usually you may have an acute versus chronic problem...acute if sudden onset, you're athletic, and catching sensation then could be meniscus tear ...chronic if onset over weeks or months and then could be chondromalacia patella , a softening of cartilage on the knee cap.
