question: I am 5'6 and I weigh 160 (female). I have a history of sports induced asthma and actopic dermatitis. I have these red bumps on my stomach, back, waist line, upper legs, and arms. They are not itchy and they do not burn. However, when I run, my torso and legs burn. It started out as one bump on my leg with a black center and then spread to the other spots. That original bump on my leg grew, dried up, and left a scar even though I never scratched it. I have had the chicken pox before.
