He very casually dropped into a message that he'd been for a PET scan today, context was that he was feeling stiff and tired and might skip something planned (not with me) after having to stay still for a long time.
This is someone I'm in touch with almost daily and I had no idea he's been seeing HCPs of any kind.
So, I asked if he's OK and he just said "all good". I replied again asking what it's all about and he hasn't answered. He's usually very quick to answer.
I'm not generally one to pry and wouldn't ask about someone's medical info unless they offer it, but he did tell me initially.
What would you do next? Just leave it? I won't message again, but I'll see him tomorrow, do I mention it? I don't want to seem uncaring, but neither do I want to poke my nose in where it's not wanted. I'm also genuinely quite worried.
