Hi. I have been very confused about symptoms that I have been having on and off over the last eight years. Any advice would be greatly appreciated. I was very healthy up until age 20 when I was working out at the gym i noticed my vision was becoming blurry. By the next morning I noticed a big bling spot in my left eye. After a couple of opthamologists I finally saw a neuro-opthamologist who wasn't sure whether it was anterior ischemic optic neuropathy or optic neuritis. He decided not to give solumedrol and after a couple of months my vision improved( although I still had a visual field defect). He said that it was probably just a one time occurence and it shouldn't happen again. I had an MRI and it was negative. The only other symptoms at that time were very bad headaches and episodes of vertigo. I went on with my life and was doing great until age 25 when I noticed the blind spot and blurred vision again. I went back to the neuro-opth and he said the papillitis had returned. I also started having some mild tingling around my chin , lips, fingers and toes. I also began having the same vertigo and episodes of vomiting. I had another mri which was negative also, but this time he did some more testing like vng and balance testing because he said that I had "abnormal smooth pursuit" and said that my eye muscles were weak . I was given instructions for eye exercises but no diagnosis of anything except papiliitis left eye. My vision returned to baseline and I began feeling better and forgot all about these episodes until this past summer. At age 27 the papillitis in my left eye flared up again except this time it was a lot worse. I had a blind spot over half of my visual field. Saw a different neuro-opthamologist( we moved in 2006) and he diagnosed optic neuritis. Mri only showed enhancement of entire left orbital field. i was referred to a neurologist who, along with the neuro-opthamologist ran a lot of labs, ana, lyme, esr, cbc,b12, etc. All were normal. This time I got the solu-medrol but my vision didn't return to baseline. i wasn't having any other symptoms until January when I began feeling extremely tired and my legs felt wobbly. I started having tingling in my right arm and both legs. It would feel like my right arm and right leg were "going to sleep" it would only last a day or so and then go away for a day, then come back. One time I had a burning pain in both legs from the waist down that lasted only about 16 hours, thankfully. Then I began having deep shooting pains down both arms to my hands. Also kept feeling like I was going to fall over while walking. Saw neuro again and had mri of brain repaeted, mri c- and t- spine and lp. All were normal. Neuro wanted mri of 3T instead of 1.5T butinsurance wouldn't pay. I had a gtt, b12, tsh, etc which of course were normal again. I was still having episodes of paresthesias, and muscle weakness until about 3 weeks ago. For about 2 1/2 weeks I was also having trembling of my hands and could barely write at times. i was having twitching of my right fingers and then it just stopped! Then my family noticed that my left eyelid was drooping for a few days. Now it all seems to be gone again. I am now 9 weeks pregnant and vey confused as to what's happening. my neurologist is now going to do emg/nerve conduction studies and even suggested another mri of the brain(before i knew i was pregnant). He is baffled also. He said I am still demyelinating suspect though? and is questioning whether to start immunmodulatory therapy? I am so worried. Any advice?
