I certainly would go to your doctor and get it checked out. The concerning signs for nerve impingement include numbness or tingling in the groin or legs as well as muscular weakness in the legs. If you are having either of these type symptoms then you should get it checked out ASAP. If your symptoms are limited to back pain, then sometimes things can be dealt with with pain medications, rest, physical therapy, steroid injections, etc. Lots of options. Again, go see your doctor...
