Yesterday I did not look at my face, until 3 hours had past, but it began to itch on my cheek. By the time I could get to a mirror I saw a little yellow filled blister in the middle of a red blotch about the size of the end of my little finger. I put soap on it immediately and the blister went away but the blotch turned into a very angry red place. I put makeup over it after washing my face this morning, but it still itches almost like crazy. I can handle the itch, but it is a nuisance. Could it be a spider, could it be rosacea, could it be from a chemical you find in a salon/school where I work? I also put liquid spray benedryl on it last night also with no affect. I am sorry, I am not at my home and I do not have my credit card. Thank you anyway
