I think that's totally fine that they don't know everything. But they can't pretend that they know the answer when they don't. Pericarditis is something that can get rather serious if it's just left untreated. And I've had an entire month of it not being treated correctly. When my cardiologist told my doctor about pericarditis, my doctor even told me he'd have to look it up because he didn't know much about it. And then today, my doctor tells me that he doesn't have any work restrictions for me which I thought was odd. Every reference I've seen has said that you need to rest with this condition. And now tomorrow I have to just go back to work and I feel like crud. We have to be our own doctors, and keep pushing for them to find out what's wrong.
