Hi my name is Mitchell, for about 7 months now I've been suffering from chronic shoulder pain, after X-ray and ultrasound it's been determined I will need rotator cuff surgery, I'm currently awaiting an mri which may take some time, my doctor won't give me any pain med other that atasol 30s which hardly do anything for my pain. About a week ago one of my relatives gave me an OxyContin I believe was the name, the pill was pink in colour on one side I think it said (OP) and a 20 on the other side, it worked really well for me and my arm felt like a million bucks, how do I go about asking for a script for these ? What do I ask for?
