About a week after I cut myself on a piece of stainless steel, I noticed these small groups of clear blisters on my finger, now a few days later the entire tip of the finger is covered by these blisters. The blisters, however, do not surround the cut. I stuck one of the blisters with a needle and a clear liquid came out, I poured peroxide on this liquid and it did not fizz up. The swelling is so great that it is painful and it is hard to bend my knuckle. It also itches very badly. I have been taking benadryl and applying hydrocortisone for a few days and it doesnt seem to help. I use glass cleaner quite a bit at work, could this be an allergic reaction to the glass cleaner? It might have gotten in the cut.
