The other night I woke myself up due to me excessively itchy by my right breast. I woke up and got ready for school, but i noticed that this rash is red, small little bumps, and it's kinda blotchy. I do have an allergic reaction to poison ivy, but it can't be that, I haven't been anywhere near poison ivy. Could it be from my bra, or something else because when I touch it, it's hot and I just can't stop itching it. I think i'm going to the doctors tomorrow, but please, I can't figure this thing out.
