I was told last week after a ms/neurologist saw my brain mri from March 2016 that I do not have MS but I do have alot of spots on my brain for someone my age and that it was abnormal. She said it looked vascular to her and that I was pre-stroke and that I have alot of the risk factors. My question is I remembered months ago (after the mri) that I had an episode at work where my arm got extremely weak and I couldn't hardly lift it . It lasted less than 5 minutes. Could that have been a TIA? And if so what should I do?
