question: WOW this is amazing! I really just want an answer to why my heart is hurting, and often I feel dizzy. I am a runner, in good physical condition, but about three weeks ago I noticed dizzy spells.... now I was running yesterday and started to walk, then all of a sudden overcome by a dizzy spell which quite nearly took me out. Stupidly, as I was running home from work, I carried on running. Please give me an answer, if you can.
