How can you afford all of these doctors?  They are so expensive!!!  I wish you all the luck for your sister.  I don't know if this could help but, a few years ago, my daughter went in to the hospital for her gall bladder to be removed.  Well, they "nicked" her liver when they took out her gall bladder.  She was told that her gall bladder was severely infected and accidentally spilled some of the infected contents into her body.  She was VERY sick after that and this was 4 years ago. She still has many days of the year where she isn't feeling well.  She is not as healthy as she used to be.  Alot of days, she just lays on the couch.  I wish she would have sued that hospital and the doctor.  She has since move to another state but I sure do worry about her.
