Thanks all, for the comments and suggestions. I have been doing some research the past couple days. Yes, Doctorguest, I have had quite a bit of diagnostic workup, including MRIs and myelograms demonstrating the cervical stenosis (central and neuroforaminal at C5-6 and C6-7). I've had SSEP and EMG/NCV, indicating damage in the cervical cord and brainstem as well as C5-6 radiculopathy. I've also had an autonomic workup verifying the POTs and an adrenergic sudomotor deficit of the preganglionic type. In other words, the testing is demonstrating dysfunction in several areas (autonomic, sensory and motor), which was clear from the symptoms. The main concern is that, in addition to the POTS, the neuropathic symptoms (pain, sensory and motor deficits) have progressed at an accelerating pace over the 16 months since the original cervical surgery and have become increasingly sensitive to non-neutral head and neck positions. So, yes, I definitely think there's more going on than dysautonomia. If I could just get the neuropathic symptoms ameliorated, I would be in a much better position to rehabilitate myself and get some improvement in the POTS. I have always been an extremely active person and am a big believer in physical therapy. Thus I have diligently maintained a home physical therapy regimen (and was even swimming until March), but I have had compounding setbacks and am currently quite incapacitated. I am going to look into some type of manual physical therapy (as you suggested Emily), if I can get it arranged at home. Since my condition has progressed to such a state of incapacitation, despite my own rehab efforts, I feel I really must find a knowledgeable neurosurgeon who is not afraid to take on a complex, iatrogenic case (are there any out there?). On that note, I have done some more research on Dr. Heffez and have tried to contact his office over the past couple days. Strangely, no one is answering the phone there. Dr. Heffez Office I'd be appreciative of any additional suggestions on neurosurgeons or other advice or information that may be helpful. Jim
