Hello my question is I’m going to a pain clinic I’m on hydrocodone 7.5 mg and Neurontin 100mg 3 times a day. I take it just like it says. Today they gave me a warning and said that it was not showing up in my urine test. I do not understand I take it exactly the way it says. I tried to ask questions and asked them to do a blood test but was told they do not do that. The urine test is what they do in the state of nc. Can you tell me why this would not show up?
