I have a small but deep graze on my knee and it hurts 24/7. I put a plaster on it to stop it getting infected and rubbing on things, but not it seems to have stuck to the plaster and is impossible and extremely painful to remove. I have given up trying. I have soaked it but this hasn't helped. I mean the soft cushioned bit of the plaster not the sticky part which has binded to the wound D: Im gonna leave it i have no choice...what should i do now?
