Hi,
I feel for you!
I also had a ruptured disc at L4-5. That is awful pain. Like you said, it was agony to cough or sneeze, go to the bathroom, sit at the computer...pretty much everything. But instead of heat, which I usually love, I craved ice on that area. It was January, and it didn't even make me cold! I took a course of Prednisone and had 2 steroid shots, to no avail.
An MRI showed a ruptured disc fragment lodged in the Sciatic Nerve - it actually turned out to be a bunch of them. There was a lot of nerve damage.
The surgery gave me my life back....I still can't get down on the ground without causing more pain, but at least I'm getting out and about
, which was impossible before.
Especially since you're feeling that you might be having bladder control issues, I'd definitely get a 2nd opinion. That can be a medical emergency. I forget what they call it, but it's serious. You've got to find someone who will take a true interest in helping you here.
Please keep us posted - we do care!
Debbie
