Depends on the type of medical issue. I put the healthcare one first, but I might talk to my husband first. Or my mom when she was alive, she was a nurse, or look it up on line to see if I should even be concerned.
One thing though, I do not take a diagnosis without a test. At least not one that will have me pop more pills, or surgery, or anything, without tests and without facts. Been misdiagnosed a few times in my lifetime and went through some bad things that just made me sicker. Refuse to do that anymore.
I guess that is why I have surrounded myself with doctors who don't pretend to be all knowing and work well with one another, despite their different fields. I know I pay them, or the insurance does, but I do feel very well cared for. Nice to have that in some area of my life.
