What could cause blurred vision, slurred speech, lower limb muscle weakness for 6 hours, nausea, vomiting and confusion and then the next day all the symptoms are gone but a massive headache occurred. Disoriented to exact location and inability to form a clear thought process. All labs, brain mri s chest xrays, were all clear but now the neurologist has me on migraine medication. This episode happened in Sept and then again in Oct. Very scary. I actually work in health care but was so disoriented that I wasn t on top of symptoms to go to the ER the first time. The second time we ( me and my spouse decided not to go because I had a Brain MRI scheduled the next day). It was negative. No spinal tap was done. My PCP thought I may have had viral meningitis. I had had some jaw pain earlier in the week but no neck pain. The neurologist ruled out MS. Just wondering what else might caused paralysis for 6 hours with these symptoms without a headache the headache came the next day. I had a very stressful job and wondering if I might have had a stress TIA and wondering if anyone has any information on this? I am on medication that is causing lots of side effects and I feel causing more headaches than it is treating. Thank you for the help.
