I have had this pain in my lower back/loin-ish area for some days (read over a week).  I read some other articles and found them confusing.  I am a HEAVY drinker and have been for many years (for example I drink no less than 120 oz of 8% beer every day and some days more than 200 oz.)  This has not caused physical sypmtoms other than the; a little tired, out of focus for a few hours, and a some bad dreams.  Now I experience large amounts of pain in my lower back/loin and have no energy, I've lost my attention span, and I can't control by bowels most days.  Again I do admitt that I drink heavy, but for the last 20 years the drinking has been something similar, so why the change?  I've also lost my appitiete, food just tastes off to me ( I am a Chef for a living).  The newewst of things for me is the "full-ness" of my lungs, I feel like they are always full of fluid and can't ever cough anything up (just dry deep coughs).  Any thoughts will be heard with thanks.
