A little background- I was diagnosed with L5 S1 herniation, EMG showed some nerve irritaion, sent to PM. I had terrible sciatica pain from hip to foot when walking or standing-TENS unit & sitting were the only forms of relief. Took 3 ESI's-last one was Nov. 2- Sciatica subsided, but now it's back. Came on slowly over the last couple of days- TENS unit doesn't do anything for pain now. I don't get any relief from sitting either. My hip & thigh ache and my shin, calf, & ankle throb & burn -it feels like someone is twisting my leg. All of this is going in at the same time. Does this still sound sciatica, coming from this herniation?
