The counterpoint to your last thing is that there are also many ailments that we literally just do not have enough info about yet to have proper treatments. And if we are studying such things many doctors are not going to always be up on the latest research for that specific condition.
I have found it helpful to approach it in more of a teamwork-like mentality. Don't just read WebMD and try to diagnose yourself - journal your symptoms, observe the trends, record data. If it seems like it points to a specific condition hop on Google Scholar and look for some legitimate new research the average doctor may not have heard about. Print that out and then when you go in show them and ask questions without attempting to specifically diagnose yourself.
You could be totally wrong but with some background info your doctor is much more likely to accurately diagnose and take you seriously.
