I am new hear and have a couple of questions. Anyone have this happen to them? I have been taking norco 7.5/325 for a couple years. I take 2.5 pills at night time before I go to bed. I never take more then this. I have had my liver checked through blood work and it always comes out fine. I had an ultra sound for my liver kidneys pancreas and spleen and they said that was fine. But why do I have pain in the right upper quadrant and left upper quadrant of my abdomen and in my right flank especially a couple 3 hours after I take it? This continues on and off. It is a very dull pain, not severe. Also I notice reddening on my neck and down into my chest almost like somone who has pancreatitis, some days not as bad as others? Any help would be appreciated
