Owl,
What a difficult position you are in right now!

Jme/Jmo
Do you know, or have a way of finding out, if Ed has given permission for anyone to talk with his physician? It's standard policy for a competent patient to sign a form giving the physician permission to talk to designated people. It's done for several reasons, and most of them are for the safety of the patient.

The meds and food issue is also tied to the written permission...if it was given and there was reason to believe Ed was endangering himself, it's possible it was done.
It's very disturbing to think a pdoc would do this, but these things need to be considered...
The refusal to share information with Ed leads me to believe there may be more going on than you are aware of. Please tread softly while you get a handle on this situation.

Another thing you may want to consider is talking with your T about it. One, it can help you sort through your feelings about it. Two, he can advise you on the legality and what options you have...actually what options Ed has.
Ultimately it is Ed that would have to make the complaint about the pdoc.

A few years ago my former pdoc had several complaints lodged against him for inappropriate practices. My own experience was him sharing with me that he was suicidal, crying because he couldn't make his mortgage payment, but his girlfriend was fantastic in bed.
It took me 12 seconds to walk out of there.
He entered treatment and is resuming being active but it is under supervision.
I shared this because strange things do happen with pdocs.
What Ed is saying may be spot on...most patients don't think anyone will believe them.

I applaud your concern for Ed and your willingness to try and help him.
Please let us know how everything goes, ok?
