Numbness following C-section and pre-eclampsia

In Dec 2008 I had a c-section following an 2 week admission for pre-eclampsia.  When I woke from the anesthesia (general) I had visual problems in my left eye, my left leg was weak and the left side of my tongue has been numb.  It is 8 months later and I still have numbness in my tongue, weakness in my leg and occasionally numbness in my left hand.  I have been to a neurologist, a critical care doctor(blood pressue) and pain management doctors tying to figure this out.  I had at least 50 lab tests, all of which are in normal ranges.  My doctor told me to take B vitamins which may help with the numbness. I have had at least 4 MRI scans all of which show lesions on my brain but not in the area they are normally seen in MS patients.  My EEG was abnormal.  Following the pregnancy and c-section I get headaches like I have never had before.  They are at times debilitating, causing me to take time off of work . I have an appointment at Thomas Jefferson University later this month at their MS Clinic.  My doctor doesn't really think I have MS, but he also has no idea what it is that I do have.   Does anyone on this boad have another avenue I can persue?
Thanks for reading.
