I have a herniated disc that is pinching nerves as well goes down butt cheek down leg and bothers my hip also. I am unaware of any excersises. Have you gotten any injections to release some pressure off the nerves?
There may be some difficulty when moving once you have had one of these discs firstly put in. Your body may have not recovered yet so I would advise you not to push your body over the limit by exercising too much. This will only make the matters worse. However, maybe the disk wasn't put in correctly, as you said it has been bothering you. I would advise you to seek medical advice, as they know best. After all, you cannot trust comments on any site unless you have been diagnosed by your doctor. Try some stretches and take it easy before you start participating in some intense exercises. All the best.
