When I Was 15 I Did A Lot Of Drugs

When I was 15 I did a lot of drugs and only ate fast food. One time when with friends smokings drugs I collapsed. I was drenched in sweat and blacked out. I went home and didn't think anything of it.

I am now 27 but in the years in between I had noticed signs associated with stroke. Numbness down left side of my body. Any way I am much more healthier now. However Every time that i exercise I have constant headaches that only go with paracetamol.

I haven't got checked out for this. Do you think I had a stroke?
