That's a very interesting perspective, however i noticed that you mentioned that upon insisting, you were directed to a specialist who assisted in the diagnosis. This brings me to my previous writeup about seeking a second opinion, i don't know if you read that, i think i posted it last week. I am happy to know you understood your right and obligation to yourself as a patient to be able to insist on some of these things, we all need to learn that because health workers are human too and we can sometimes make mistakes.
Always remember you know yourself best and your healthcare provider knows the medicine, healthcare is team work between patient and the doctor or physician.
