MY MD is treating a staphwound on my elbo. It was running clear, and stopped running. He opened it up, packed it wraped it up said to come back in 2 days. I did, he unwrapped it, repacked it, and said to come back in 5 days.. This is day 2, and the bandage is dirty, should I have one of his peers to check it tomorrow, put on a clean bandage? or forget about it until tuesday?
