That sounds like a very challenging Doctor dilemma.
My advice would be to find a specialist so you can feel like you are in good hands. I think it is really important to feel like you are being looked after and to trust your health care provider, cause this is an issue that has mountains of worry and doubt. I am not sure if there is a way to "know" if you are with a TOP Best Doctor. But you can know when you are with the right doctor for you, cause you will feel more at ease. My doctor is at a University teaching hospital, I have found him to be affordable and wonderful. I would think there would have to be State University Teaching Hospitals like this in every state, hopefully you can find one and it will be good like ours.
Now for a RANT .... LOL
If my doctor ever said something so unhelpful as "check web md" , I would ask them If I could have that in writing? That sounds like something my Veterinarian would tell me to go do! I dont understand that at all. I would think 1. at least the doctor would have print out of Information to hand you, or be able to recommend another doctor who could help you, where she could not. To me on principle alone that would rock me. But, I know I can be a harsh judge.
I tell you this super long story cause to me this is an example of dealing with worry and doubt, with a Good doctor I feel well matched with.
I had an issue with my doctor, -- I found out about a NEW prescription vitamin made for women with MTHFR like me,, my doctor currently has me on OLD school vitamins of just folic acid. So I called the office and asked his nurse if I could be put on the FANCY NEW vitamin, she called me back later that day and said NO go , my doctor wanted to keep me on his original prescription of folic acid. And when I asked how come, the nurse said because he trust, knows, and has good results personally with just folic acid, and that he would get more info on the NEW vitamin I wanted, and maybe we could give it a try or add it in, he would tell me more on my next visit. Part of me I wishes I had a doctor who was enthusiastic about new things but then I recall things like DES, and I appreciate his reserved ways.
