Hello Doctors, I took five 5mg oxycodones throughout the day yesterday, and today had a pain management appoint today. They did a drug screen today I m worried about the results, because it was not prescribed to me. I had my last test come back for that, and I let the doctor know that. I have been under pain m. for 20 years, and have never had one come back for anything other than what I was prescribed. I have chronic pain, and Lupus I have lost 75lbs . I use to weigh 375 now I m 270lbs I m 5 11 I drank a whole lot of water about two-gallons. My regular meds are methadone, and hydrocodone. Could you please let me know
