Please see a doctor and get an immediate referral to a gastrointerologist. Do not self diagnose, there are many serious conditions that can cause hear symptoms, and this could be life threatening. This is not something you can afford to wait on, if need be go to the emergency room.
I am familiar with that condition and it's horrifically painful, but you may have other things going on. I was a heavy drinker averaging 24 beers a night for several years. I eventually switched to hard liquor because I could not physically drink or contain the number of beers I needed to get drunk. I chronically had swallowing issues, stomach pain, vomitting blood, black tarry stools, etc. The hard liquor was eating me from he inside out, and eventually I suffered severe internal bleeding. I always ignored the symptoms and blamed it on my drinking and that stuff was irritated. I was partially correct, it was definately irritated, I had a steady bleeding ulcer, open wounds on my esophagus from constant vomitting and then drinking liquor, I had severe intestinal issues where they would stop moving at times and I would become obstructed, which lead to wounds on my intestines, but I was always too drunk to really notice the bowel problems so it became severe. I colon was rupturing, and my stomach was pretty close perforation. The alcohol numbed the physical pain so I had little biofeedback to indicate I was in serious trouble. Had I waited a day longer I would have died, and I only went to the emergency room because my family was concerned about the bleeding. I was actually bleeding significant amounts but was not aware of the amount because I was constipated, and noticed my stool was back but did not realize much of it was blood because I only glanced before flushing. I ignored the fever because I was drunk and was always warm when I drank.
The point that I am trying to make is that your judgement is clouded because of booze - go get checked out by a professional ASAP!!! Do not ignore it or minimize it because of booze - booze may have caused it but that doesn't change the situation. Regardless, stopping drinking is definitely a good choice as you are destroying your body. Please let us know what you decide to do and how it goes. Good luck!
