Re: soar back all over
If I were to hazard a guess, having the same kind of radiating pain from an L5-L4 disk herniation and tear, I'd call it muscle spasms. A good drug for that is Valium, which also acts as a mild tranquilizer and will reduce the stress you are feeling.
Unfortunately, Valium is very addictive and getting off it can take a long long time. There are other drugs out there that also might help. Soma, Flexeril, Zanaflex, Skelaxin etc... but none of them ever really helped me.
Talk to your doctor about this and good luck!
