Using 10mg. Hydrocodone from a car accident a year ago. On and! Is this a common side effect using / daily basis 10mg hydro?

Narcotic dependency. Hydrocodone is prescribed to treat moderate to severe pain. It sounds like you might develop dependency to hydrocodone. Please discuss it with your prescribing doctor to see if you would benefit from evaluation from addiction specialist.
Chronic hydrocodone. I would be very careful, but i would try to taper off this narcotic under a physcian direction. Daily use of hydrocodone (vicodin) has many issues in the long run.
