I am on the side of "probable MS", although negative MRI's according to my neurologist and scheduled for 4 sets of evoked potentials in a few weeks. Last Thursday I had a sudden onset of mid to lower back pain, and shooting pain down my back when I lowered my head. I was seeing stars! I left work and cried from the pain for 2 days, before the neuro ordered some muscles relaxers and neurontin. I finally have some relief but am having extreme difficulty walking. I had a lumbar MRI yesterday because he thought it was maybe a herniated disc. My question is this, if there is no sign of a herniated disc what in the world is happening to me? My entire torso is spasming, it feels crazy and the pain when not on the meds is worse than giving birth to my kids. Anyone ever experience this? Or anything like this?
