I had Spinal Fusion on C-5/6 in 2004 and further surgery to fuse C-4/C-7 in 2013. Am still having pain and numbness in my left arm and neck. Started Physical therapy three weeks ago and things seemed to go ok. Last week I went into the session feeling fine but was unable to sit, see or stand for a considerable amount of time after the session ended. It sounds like Vertigo but it makes no sense that the therapy session would have caused it. In the 8 days since then I have existed on Valium and Prednisolone and am in constant discomfort. I will have an MRI on Thursday but am trying to figure out what could have happened.
