So I made a big mistake of not using sunscreen the other day and it’s biting me in the ass right now. I’ve developed tons of blisters over both of my shoulders that are extremely painful and annoying. Went to urgent care and the doctor prescribed me Silver Sulfadiazine cream to put on twice a day. So, has anyone dealt with this before? How long before the blister pain goes away? I’ve been using the cream the last few days, but it doesn’t provide any pain relief. I think it’s just there for possible infections. I can barely extend my arms straight up without stinging pain.
