My questions is this: I've got an S1 radiculopathy caused by a tarlov cyst on the nerve root. A month ago my primary complaint was hamstring cramping, but now it seems to be affecting the gluteal muscles more than the hamstring. There seems to be some piriformis involvement (but it is not a "piriformis syndrome" because the nerve root irritation is causing the piriformis to cramp rather than the piriformis causing the nerve root irritation). I know for piriformis syndrome they can can inject the muscle to give relief. I was wondering if with a neurological cause there would be any benefit to trying either gluteal trigger point injections or a piriformis injection? Has anyone with radicular symptoms done any type of injections to help with the muscular pain? I'm not sure if there would be any lasting benefit since it wouldn't really correct the underlying nerve problem...Of course, this is something I'll ask my doctor about, but it helps to hear if you guys have tried anything like this.
I am currently in process of moving forward with scheduling a SCS trial, but we are hoping that maybe since the leg symptoms came on insidiously they might resolve enough to where I could possibly just need leads to cover my low back. My thought is maybe if the gluteal muscle pain can be treated with injections that might put me closer to not needing leg coverage with the SCS? My hamstring cramps have responded well to a muscle relaxer, and the burning pain down my leg has improved a little with oral steroids, so now I just need something for my butt muscle pain
P.S. Does anyone know the mechanism of action for why nerve root irritation causes muscle cramps? My guess is that erratic nerve impulses set off action potentials in the muscles causing them to fire and cramp?
