Sunday I took half a 10mg hydrocodone then my friends called me to go to the bar. I ended up blacking out that night. Did not drink Monday, but drank about 7 or 8 beers Tuesday. That night is when I felt sharp pain in my upper right chest and my right shoulder. Today it feels a little better, but both are still bothering me. Could it be my liver, or some other problem? Should I see a doctor tomorrow if it still feels bad?
