I'm having surgery next week and am paranoid about being in pain as I recover. I already take controlled pain meds for my post-chemo joint pain and torn meniscus in my knees. Question-when I tried to refill an old Norco prescription at the pharmacy today, I immediately got a call from my new pain management doctor's staff asking why I was getting pain meds from someone other than their doctor. How did that pharmacy even know that I went to the new pain medicine doctor? I never told them. Am I on a list somewhere in pharmacy-land? Is this a violation of HIPAA?
