Pain under my left rib cage i take a lot of hydrocodones?

Impossible to say: Without a full examination. Hydrocodone does not come alone in the us - it is mixed with Acetaminophen (tylenol (acetaminophen)). If you are taking too many (more than 4 grams per day) you can get liver damage from the tylenol (acetaminophen). See a doctor or go to an er asap to check this out, as liver damage from tylenol (acetaminophen) can be life threatening. If you are prescribed the med, talk to your doctor. If not, get help; detox.
