I'm terrible at first aid stuff and have no idea whether I'm doing the right thing or not so though I would consult mumsnet wisdom.
I cut my ankle last weekend (took a chunk out of it with my razor- literally, had to pick the chunk of skin out ). Put a plaster on and have changed it a few times as an scared of getting sock fluff in it. It still hasn't scabbed over and in fact just started bleeding a bit again when I took the plaster off. Should I be worried/be doing anything to help it heal?
Get some melolin. It's a dressing with a non-stick side on it. (You can buy it at a pharmacy.) You do need to let it dry out, but obviously protect the raw skin at the same time. Get some paper tape or plaster roll to hold it on.
