When I work out, I often go into this crazy heat stroke thing where I get big red blotches on my skin where I'm extremely itchy; like a thousand poking needles itch on my stomach, chest and back. This even happens at work. It doesn't always happens and ranges in severity. I also have another symptom which I don't know is linked to this but I suffer from numbness. Most numbness is in my jaw and arms. I told all my symptoms to a doctor and they tested for Diabetes and MS through a spinal tap and nothing turned out. Through personal research I'm thinking something linked to Celiac Disease? Chronic diarrhea and acne are also prominent. Heh a tall order I know, it's even stumped doctors I've visited. Any ideas?
