I know Lisa, it can be confusing. It is a stressful process when you are in the midst of decision making. Once you decide, I think you will have more peace. One thing I did, and have just recently done, while trying to make a decision, was to look at many different situations and outcomes on this forum and who they had used as their physician. You can search out the doctor's name in the Search tab and look at past discussions. You can probably also find comments about them through a Google search. I find that quite helpful. Also, I think of it as a one time deal (hopefully) and just want to search out the doctor that has done many AN treatments and is considered "great" in many eyes.
I really liked Dr. Friedman on the phone. That is my extent of contact with him, thus far. I did appreciate him volunteering to look at my MRI in July without me having to ask him. Also, I appreciate him not jumping to me needing surgery. At least he thought my situation over. That says a lot for him.
Good luck to you Lisa, as you make your decision. I wish you the best in your treatment.
