Question about abdominal pain?

So I have been having right side abdominal pain that started 2 years ago that I noticed would get worse after a bender, I went and got my blood done plus liver scans and they said that it all looks fine, Checked for gall stones and they saw nothing , I know drinking makes it worse for the few days following but I don't know what I'm dealing with , The pain is a sort of dull discomfort if I was to describe it. Does anyone else experience this or have any ideas?
