No harm in learning a bit about it yourself though. I don’t mean you should argue with the doctor or tell them what you think is wrong but to just have a bit of an understanding of the issues your body is facing.
It’s best to go to a doctor with an open mind, don’t try to guide their thought process and let them work as they work best. But if you take responsibility for you body then you’d better reconcile what they say with some common sense.
Hope you find your answers and that you keep us updated.
