when I was 18 years old doctors thought I had a TIA, 2 weeks ago I went to the ER for a headache i was having for 1 week, numbness/tingling down my right arm. Now, i am having numbness/tingling down both arms and legs, and I have a shotting pain down my left arm. I still have the headache as well. dizzy spells, some blurred vision. the ER doctor think i may have MS.
