QUESTIONS ABOUT REVISION

Samantha, you need to call the Customer Service people of your insurance company and ask if they cover revisions.
I am so sorry you have been having such a horrible time. You must be so exhausted and frustrated. (((bh)))
I don't know where Sheffield is, but I assume it is a small/medium-sized town? Do you have access to a larger city and a wider field of medical professionals? I am thinking even Atlanta? Even if that is a far piece to drive, it might be worth it to escape this medical hell. Why don't you post on the Main Board and see if you can get recommendations for doctors/surgeons? I wouldn't even worry about losing weight or a revision until you find out why all these things are going wrong. Weight loss isn't going to do you a bit of good if you are too sick to enjoy it!
Good luck!
