Kidney & Liver Pain

I'm concerned about my kidneys and liver. Lately in about the last two months I have been having internal pains on both sides as well as in my liver area, especially days after I drink alcohol. Even small amounts. I was diagnosed ppd positive in oct. 2005 so I took the medicine to eliminate the tb bacteria for 9 months. I finished the medicine in july of 2006. I was hoping for some information and/or advice on this matter to clarify why I have these pains that seem to be happening more frequently as time goes on.
