I Was Diagnosed With A Mild Stroke Last Year Which

I was diagnosed with a mild stroke last year which caused the left side of my body to be "numbish." I still hae some feeling on my left side though. I am 70 now. I take warfarin. I have lost about 50 lbs. I am 5'3 1.2 and weight 168. I used to weight 222. Is it possible I could have another one, a major one? Thank you.
