Like "If it's that on going, I would definitely have it checked out. If you don't want to go to your doctor, then go to the hospital to have it looked at. Waiting too long can lead to all kinds of nasty. My step daughter had what we thought were bug bites that would not heal and it turned out to be MRSA. THAT was nasty to deal with. So far, I have not had anything that won't heal, but I always keep an eye on it and if it takes more than a week to look better, it needs some help. Being "chicken" is understandable, but don't let it ruin your life. Things that don't heal lead to worse complications if left untreated. I would be more afraid of the consequences than the diagnosis."
