I had a fall last week and scraped my knee the size of a 50p. I have dressed it when going out but it sticks to the wound and then tears it open again when I take the dressing off when I get back home. I have left it to the air as much ad I can but seem to beer in a vicious circle of it healing a bit and then opening up again. I just googled and it said a lot of people put vasilene on a wound while it is healing as this is is better than letting it dry out - has anyone tried it and knows if it works better that way?
