First, I am so sorry this happened.
I would be willing to bet this is more about them covering themselves then a judgement on you..
HIPAA? what a joke.
I don't know a few things...did you go to the clinic that employs your doctor, but see another one because your doctor was not in? Are they connected by your insurance, or anything else you can think of?

It is discouraging when you have taken good care to be responsible with your pain relief and this happens....I have another thought.... Is it possible that some of your refills were called in, to oh, say "helpful Walgreens," and they contacted the doc? They are not supposed to, but they do, all the time. If you could lay things out a little clearer, without compromising your security, we might be able to offer you a more informed opinion.

Welcome to the board, again sorry that you are going thru this.
