A few months ago I noticed a few "bites" on my buttocks. They don't itch, but they hurt. It's not all over, just on a specific section of my back side. If I go to pop them - the "puss" is hard and white, or none at all. I disinfected my whole house and change my sheets almost everyday. Could it be allergies? I do have seasonal allergies - but I've never had actual bumps before. And if they are - how do I get rid of them. I'm allergic to the following : Timothy Grass, Maple Leaves, Dogs, Cats, Cockroachs, Mold, Pollen, and Hay Fever. Please someone HELP!!!! Thank you so much!
