I recently scrubbed my face with antibacterial soap and had a cold causing me to blow my nose a lot and all I had was paper towels at work. Could the irritation have caused a fluid filled blister? I recently had a wart close to the same area on my nose, which was frozen off. Will a blister bleed for a while after if the cover is picked off? Or could it have been another wart? Can a wart look like a fluid filled blister? Would a wart appear overnight?
