I've been taking norcos (hydrocodone and acetaminophen) for 6 months now and now i'm starting to get foot pain even when i take it. what could be wrong?

Norco (hydrocodone and acetaminophen) is a narcotic: And it is habit forming, therefore its effectiveness goes down with prolonged use, while dependency and addiction can become an issue - see your foot doctor for the real therapy and to get to the root cause of the pain!

Narcotics: As dr glukh stated , these are habit forming meds with diminishing return because of that. The source of your pain needs to be found - see your podiatrist for help
