Today I was using my soldering iron and I moved my left hand and touched it by accident when I was desoldering. (I know it was stupid) It hurt for a while and I had my burnt thumb under cold water for 5 minutes. The burn made my skin turn white and I put on a band-aid. 30 minutes later I noticed it didn't hurt anymore and the white skin became a white blister. Should I do anything else to treat it? It currently feels a little numb but nothing to bad. I also applied solar Cain (again, I don't know why I thought that would do anything xD) I never burned myself before with a soldering iron and it would be nice toknow if I should do anything else. Thanks!
