The blister got bigger, but I believe that to be because my ring was probably chaffing it. about three days later after just leaving it alone and covering it with a band
aid, it ruptured while i was washing my hands and changing the band-aid. This was not painful and it healed fully leaving a flat smooth scab. The reason I ask about this may be crazy but, when i showed it to someone at work, thinking I must've burned myself, they said "Maybe it's herpes?
