We changed Doctors recently, in a nutshell this was one of my best decisions in a decade, After a visit with the wife scans arranged, specialist appointment made and a diagnosis all within a month .
The news was not brilliant but it answered many of my questions .
Changing Dr's was the best thing I did back in the day, like you everything was arranged for me after that. Same as you the news was not good but it mean't there was clarity and it enables you to move in a new direction rather than being stuck and going round in circles. I think a lot of people should change Dr's because it's a serious step in the GP world and you are taken more seriously by doing it.
So glad you got some answers.Drs do get stuck in a rut and good to get fresh eyes on the situation if you can.
You have some idea now and may find it easier to find out what may help you, even if in small ways.
Very frustrating not to know and wonder.
