Hello, i know this isn't really a medical question but me and my mother need some help. My mother a month ago did a drug test and failed it, to her surprise of course. She has never done any drugs, but her drug test said that her pain pills weren't showing up so she is denied any pain pills though she always takes her pills, she asked a nurse and the nurse said with such a low dose (5-325 hydrocodone) it might not show up. The doctor won't give her another drug test, and when my mom asked for a different doctor they said they can't give her one without the other doctors permission, who already said no. And i was wondering, is this possible? I mean my mom is on disability and needs them for her legs this just seems absurd.
