My mother had a quad bypass in 2009 and now may have an infection between her breasts. Doctors say that the she never really healed and that there is a gap where they made the incision. Is this common? She is having an MRI done tomorrow to see if they need to open her back up to remove the staples. She is 62, diabetic with rheumatoid arthritis. She is more concerned on how whe will pay for everything rather than getting well. Any suggestions?
