Hi Doctor. I have an abrasion from a car accident 2 weeks ago that looks like a gash. However it is not like a deep cut. I think an object must have hit it hard but did not penetrate too deep as I was wearing jeans. It's about 3cm long and 1/4cm wide. It seemed to be healing and there is even a thick scab on the surface. But I noticed a little pus coming out from the sides over the past 2 days. I am using Bernadine to clean and I leave it open without covering. Please advise if i have any worries. I will try to send a picture.
