I ve recently been getting these red spots/bumps on skin that is usually covered by my clothes. Skin that is exposed to the sun isn t affected. At first I thought it was just small pimples on my skin, since I have been just recently started exercising and sweating a lot, and I just haven t been washing properly, but a friend of mine saw them and said it looks like some type of food poisoning. Looking at a few things I have been eating recently, I have been eating things like sushi, and meat that is cooked to about medium-rare. There isn t any type of itching with them, they re just there. Should I be worried?
