Hi, I really don't know where to turn to or get answers, I am on meds for depression, HBP and chronic pain, I take generic Effexor er 150 mg 1 x daily and clonazapam 1mg 3xd for depression,3 bp meds, and take 30mg 3xd and percocet 10mg 3xd, I was recently drug tested in office and showed positive for pcp and methadone, I also take tylonol pm at night and advil, they sent me straight to hospital for blood drug test and it come back as having nothing at all in my system but also did not have a list of meds to go by, I am going through very bad withdrawl , I went to er with bp 220/111 and I told them what was going on at the docs office with my meds, I don't understand how one test can say one thing and another reads nothing in system, My doctor there had resigned a couple weeks ago, I had just found this out and the doctor they give me will not see me till end of august, I spoke with a nurse from my ins. and she said to go back to er that things can change and could still have a heart attack, I still am taking what I have left of my depression meds but they won't prescribe me clonazpam anymore or pain meds. I have a lot of back problems along with artho in back and in knees and have had surgery done on one knee already, I don't even want to go back on morhine because of what I am going through now, But can anyone explain why my tests showed up like that please? and how long does withdrawl last? it has been over a week now and just keeps getting worse, The doctors office will not even talk to me about this because they think I am not taking meds... PLEASE PLEASE HELP.....
