I was diagnosed with MS in 1996, presenting with grand mal seizures, had MRI and L.P. have been on 400mg/daily Tegretol since, in remission until this year, diagnosed with Paratrigeminal Neuralgia in Feb. 2007,ice pick pain in right temple, drooping left eye with numbness in left side of face, was given IV Steroids, weaning Prednisone increase in Tegretol gradually for pain, tried Topamax, didn't help symptoms, started on Neurontin, increasing dosage to 1600mg/day which is what I am on now along with 1200mg/day Tegretol, 6 Extra strength Tylenol/day. Started suffering from severe pain in hands in July 2007, x-ray done, normal. Started suffering from severe muscle spasms in legs in July 2007, October MRI of spine & pelvis, normal. Began suffering from severe vertical double vision Nov. 7, went to ER, CT done, normal, Tegretol drug levels done, normal. My question is this, what might you think may be causing the severe vertical double vision? I was told by the ER doctor that this is not normally a symptom of MS and since there was no pain involved it makes it even less likely to be part of your MS. Thank you for taking the time to answer my question.
