I had my 3rd MR almost 30 days ago. My first TT my BB was perfect. Now this time I think there is necrosis and infection. It SMELLS bad. It oozes stuff out of it and is bleeding. My surgeon has me coming once a week for him to change the gauze and I think he stuffs the belly button with Neosporin and packs the gauze in. My concern is its not healing and today it was bleeding. I don't know what I should be doing my surgeon have me no instructions on how to care for it at home. Suggestions?
