I had a similar situation with a mental health worker in the hospital. I asked him if it would be inappropriate to have contact with him outside the hospital. He gave me his email address. I only emailed a few times, but I found his FB page and referred to it in my email. I told him I wouldn't friend him because of privacy and that I had a couple of other patients in my friend's list. Then I emailed him because he seemed sad in his FB posts. He then made his FB page private and never emailed me back.

The difference is that I may not everr see him again unless I go to the hospital, and I don't know if we would even have to talk about it.

I hope you get to talk to your p-doc about it soon.
