Apologies, I wouldn't usually ask on a forum but at 40, I'm woefully inexperienced at first aid! I burnt my arm on the oven shelf on Sunday, cursed a bit, ran it briefly under a cold tap then carried on serving tea, as women tend to do. The next day, it had formed a neat brownish mark but was quite flat so didnt think it had blistered. Im working from home so have just left it uncovered but careful to keep it clean. Yesterday, I accidentally rubbed it and the thin soft layer came off, leaving a pale pink 'raw' bit underneath. It started to sting but I put a bit if Savlon on and it's been ok. Just had a shower and noticed it's a bit yellowy and the skin round it is pink and slight raised. It's not particularly sore. Do I leave it uncovered or shall I put cream on and a plaster/dressing? Do i need to be keeping an eye on the raised red area in case it spreads?
