I got 3 bedbug bites in a row close to the inside of my breasts about 5 days ago. very red and itchy and when I applied fucsidic acid/hc acetate and I am not sure but it blistered into several smaller ones. around the redness and bites, Then unfortunately 5 days later I got bit on the lower labia major. and saw the bite, then applied the cream and several small blister appeared.. so i know bedbug bites can blister as I have been bitten so badly in the past while traveling. I swell and get so red. had a few blister. but I was thinking maybe the cream was to strong. but I use this cream on cuts and things when I need to get the inflammation down. what do you think? I am not sexual so I know nothing could cause the blister after all I saw the bite first.
