I occasionally have pain after drinking alcohol. why?

Pain where??: If you ever put alcohol on a cut, you know that it is toxic to tissues - it burns! That is not just true of isopropyl alcohol but ethyl (beverage) alcohol as well. People can get pain in their mouth and throats, esophagus, stomach and duodenum from drinking excessive alcohol, or for those with particular sensitivity. It can also inflame the liver and pancreas, causing abdominal and back pain.
