As a child, I was diagnosed with a condition that required me to eliminate all exercise and strenuos activity. The only sympton I recall having was tiny red dots/spots all over my back and back of my legs. Do you know what this condition is called? I remember there being three parts or words in it, but that's all I recall. I wish to donate blood, but given that I have this in my medical history, I am not able to donate until it I can provide the name of the condition.
