I am 30yrs with moderate Hep C. I broke my hand and was prescribed norco 5-325s. They made my abdomen swollen and gave back pain. Then I was prescribed tylenol-codein 3s. They don't work so I decided not to take anything. My pain is more annoying than unmanageable. Tomorrow I am having surgery. What is the most effective narcotic that's safest on my liver and system that I can take temporarily. Also is it safer to take a stronger narcotic than take a safer less effective narcotic more frequently.
