Wow. We see the GP our postcode determines.
I'd never even heard of an internist.

No help to you, Lola.
All I will say is when other people are offering their advice be aware of the why.
I've known some parents who consider a good Doctor to be one who gives their child medicine every time they go with a complaint. Hello? Way to make antibiotics disease resistant. Ditto anti-depressants used as a placebo. And yes, I take anti-depressants, so I am not questioning their value where necessary. But hearing someone say, "I knew today would be a hard day so I took extra Prozac [or whatever]" does make me cross.

Of course there is the flip side where a bad Doctor dismisses important symptoms. Again and again. Sadly seems more prevalent for women as they get older, so many cases of late-diagnosed cancer et al.

So just good luck and keep asking questions.
WHY is an important one.
