I started using Dymatize Elite 2 weeks ago, this week i noticed some bumps on my arm, if i touch them they get red and more swollen and itchy, basicly this started happening all over my body (legs,arms,back,core) and it's really irritating, has anyone experienced this? i think it's my whey, as this happens more often after taking my shake, i really dont feel like wasting a 10lb. bag, thinking of just sticking through these irritated/itchy/swollen bumps?
