I have a dull achy pain under my right rib cage, presumably where the liver is. It hurts most when I cough , sneeze , or laugh. I have been somewhat a heavy drinker for 6 years, on and off, and have been drinking more heavily this past month. Could the pain be related to this? I am a 30 year old female, and have been known to be a hypochondriac, so wonder if it could just be in my head.
