<<Disclaimer: Verify this information before applying it to your situation.>> You mention that this pain occurs particularly after drinking coffee or alcohol. I may be way off base on this one, but a pain in the left side, just above the belt, that worsens upon drinking alcohol could possibly be an indication of a little pancreatitis. I'm not an M.D., so I want to reiterate that I could be way off base with this 'diagnosis'. Barbara Kuehl, Ph.D. Dept. of Educational Psychology University of Wisconsin-Milwaukee
