That sounds very unsettling and scary. Big hugs to you.
Last year my T had major surgery. It was a different than your situation because it was planned and I knew ahead of time that she'd be out for at least a month.
I think it's always ok to let someone know you're thinking of them during a difficult time or physical illness. I sent a Get Well card to my T's office. I didn't really know if she'd get it, but I figured she would have to have someone pick up her mail. And it made me feel better too.
I think it's a thoughtful gesture and would be appreciated by your pdoc.
Take good care.
