Find a new Dr. You may need to see a pain specialist if your family Dr doesn’t treat pain. My Dad had the same problem and his Oncologist told him he didn’t treat pain, but he referred him to a pain specialist. With all the negativity about addiction and over prescribing I think a lot of Doctors are afraid to prescribe pain medicine but make no mistake, your Doctor was rude and uncaring to snicker at you! Your pain is real and you need a Doctor who understands that.
