Hi,
I get very lite headed after walking up a couple of flights of stairs and this occurs about 80% of the time. I then get this very warm feeling and I do feel as if I could pass out as I can feel as if I am in a tunnel. I have never passed out but I feel this way. Only once have I had a head ache after this event.

I exercise 5 days a week. I play racquetball at a very high level of skill as I am an A player. A is one level below a professional. I also lift weights 4 days a week and walk about 2 miles each day.

Thanks
