After failed back surgery, I was referred to PM. This was about 1 1/2 years ago, neuro stimulator placed doing well with pain control using ibuprofen and Tylenol #4. However according to PM Dr. last 3 dit have shown increased amounts of hydrocodone. I take ibuprofen, Tylenol #4, Prozac, diazyde, devastating, multivitamin, exception, and a topical compound which is formulated under Dr. order. I do not take hydrocodone. I am allergic to hydrocodone. I am at my wits end, what would cause this false positive.
