FReepers mentioned that Rush had talked about back pain during his program. He may also have said himself that he is taking pain meds for it.
If Rush has said it on the radio, I don't think confidentiality is an issue.
BUT.....they implied he told the ambulance people that “I’m on meds for back pain” and then ABC continued to his substance abuse issues....
I heard him when day when he was in severe pain and he remarked that, “I can’t take painkillers.”
Whether he got desperate enough to take something, I don’t know, but I doubt it.
