I am a 27 year old female who has been told that I have had 2 mild strokes(tia's). Every test I had has come back normal, from mri, to emg, to echocardiogram, blood work, everything, normal. They dont know what is cassing them. I was told that you can have several of these types of strokes and not even know it until you have the big one. My whole left side went numb two weeks ago, and now I have physical and occupational therapy, but they still dont know the cause. I am so confused and scared.
