Ugh!
My sisters husband had open heart surgery and he went to his primary doctor bc he wasn't feeling well due to a cold and his docotr listend to his heart and said that it didn't sound good to call his cardiologist asap and the Idiot scared the life out of my brother in law and it was NOTHING!!!!! So I can understand how MAD you must be. I hope you find a qualified doctor sometimes it is so hard.
I myself have had a few bad expierences with doctors. It makes you nervous. I will pray that God puts a good doctor in your path
