Can a compressed sciatic nerve cause leg weakness? Specifically the hamstring?

What can cause bi lateral generalised leg weakness with difficulty to step up without grabbing pain in top of leg. R worse and calf mus hurts?

Your doctor will likely perform a neurologic screening exam, and possibly recommend a ct or MRI to rule out spinal stenosis or other nerve impingement problems. You need to be seen about this. Good luck. Lgromkomd. ...Read more
