Hi, I have a wound on my foot. I scratched it on a piece of rock while in the sea. It started as small scratches - 4-5 ,they were very small but after the scabs fell off, a big one formed combining all of the scabs into a 6mm one. I peel off the dry part but it keeps drying continiously. The wound is dry and when I peel it off, normal skin is underneath. But after a day, the dryness come backs and the process repeats. This has been here for a month. Is this anything bad?
