Patient : I fell last Wednesday morning on asphalt and i'm left with a big but shallow scrape on my knee. I had antiseptic and gauze on it but after a day I took the gauze off so it could air. A day later, it started swelling. I bandaged it in hopes of bringing down the swell. Two days later, it stopped swelling. It also stopped bleeding. However, ever since then. my mom has insisted that i leave the bandage on and every day, she applies a new remedy to the wound because the previous one didn't help. Every day when I change the bandage and gauze, it oozes pus. I think most of these remedies would have worked if I had let the wound air. What should I do to treat the wound?
