Hello tj71: I'm sorry I cannot really offer any suggestions as to what may be going on with you. But I thought I would simply welcome you to NeuroTalk.

Hopefully other members may have some insights to offer.
You & I do share a couple of similar problems. I have a ruptured disc in my lumbosacral spine that impinges on the sciatic nerve. So I have sciatica. I also experience heart arrhythmia. I have tinnitus (& Meniere's Disease.) And I experience kind-of a "low-grade" sort-of trembling feeling throughout my body 24 / 7. It has been suggested to me that this could possibly be due to a magnesium deficiency. But I don't know. I haven't sought any treatment for it. I'm an older person. I avoid doctors as much as possible.
