Would really appreciate some advice. DD (age 17) had a blister from a burn, about the size of a fingernail. The blister burst during the night when she rolled on it. The skin has all come off. It doesn’t look infected. Should she cover it or leave the raw skin open to the air? It’s not covered by clothing (below her neck). The nurse at the GP surgery gave her some dressings to use if it was weeping, but it’s not weeping. What do we do? Don’t want it to get infected or scar if possible. Thanks.
