Hang in there Lori, things happen for a reason. At this point maybe you can call your new PM doctor and explain what has happened with your primary Dr. and see if he can admit you to the hospital and while in hospital begin the search for a new primary care doctor. This old Dr. seems like a jerk anyways. He could have killed you with the medication combo and contributed to that swelling in your abdomen, who knows? Right now is a tough time for you but it is also the time you need to be the strongest to fight for yourself and your treatment. KEEP FIGHTING, you will get there one battle at a time.
I will think of you along the way!
