It would be hard, but not impossible for your PCP to find out about OP usage. This is not what you asked, but I hope ya'll are aware you are more than likely double dipping. If you read the fine print on the OP's agreement, it says that you agree that you are not getting the same medication from another doctor.

I'm not placing any judgement, I just wanted ya'll to know.

You could always look for a good Pain Management Doc, or just order from OPs to rectify the situation.
