If you paid to have the surgery, then he owes you to have the surgery performed. It sounds as if he knows he performed poorly on your lipo and knows he needs to do a re-do. Not sure what two medications you would prescribe before surgery (unless they were antibioitics), but it certainly sounds as if he, in actions is admitting wrong doing. I would keep pursuing this. Doctors are not to be put on pedestals. They are not perfect, they are not gods. They make mistakes, they cheat, and they lie, just like everyone else. Keep calling the office for a follow up appointment and let them know that you intend on taking this to the State Department of Health as a complaint. Then go on line and register a complaint with your state's DOH on this doctor. It may not be the first one either. Again, most doctors are honest, caring individuals. But, there are always a few bad apples in the bunch.
Take care and I hope you get your issue resolved.
