Years ago, while on vacation in Hawaii, I got a really bad sunburn. They had what they called “dial a nurse” who basically did just that. Asked questions, and did an evaluation over the phone telling me I had what sounded like 2nd degree burns and I should soak in a cool bath to help with the pain and if it didn’t feel better in an hour, to go to the ER to have a further evaluation. The cool bath worked and I didn’t need to go to the ER but when I got back from vacation, I had blisters on my next so I went to my GP. He said they were 2nd degree burn and the cool water helped stop some of the blisters but the ones I had were at my neckline of my bathing suit. Antibiotic cream and pain meds if I needed them and I was all better. I think if makes sense it is ok to do it but just be careful if they have you mixing potions in the sink—voodoo and witchcraft are everywhere. I will have to check it out to really give a final opinion.
