I've never met a doctor I didn't trust more than the internet, but you raise an excellent question. How DO YOU know if you are getting the best care... or even good care? Four surgeries seem to me to be over the top, and I'm so sorry you went through all that. I guess my answer is found here on this web site and others like it. For people with MG, their best resource is other people with MG. Hearing others talk about their various treatments, the drugs they are given and the results they get, provides a way to measure your own treatment. Not every doctor is a miracle worker, and sometimes it pays to shop around. I'm currently on my third neurologist, and he's wonderful. I'm glad I was not satisfied with the first two.
