I'm sorry to hear of your concerns about pain and numbness. None of us are doctors so you have to take what we say with a grain of salt if we make the mistake of trying to diagnose a medical problem.
I'm a long time member of this group that nobody wants to be a part of so my very best advice is that if you are still having these kind of symptoms you would be best served by seeing a neurologist who has handled CES and other back problems. The sciatic nerve can produce some of your numbness and pain so don't worry unless you are given reason to, okay?
Best of luck to you in finding answers to quiet your fears.
