See a doctor: You need to be examined and your underlying health issues are very important. It sounds as if you have esophagitis. Do not delay. Go and see a gastroenterologist or your pcp and they may want to refer you.

Need attention: If you cannot even drink you need attention urgently. If the pain in your "food pipe" is deep in your throat, it's likely a throat infection. If the pain is down in your chest, it may be a true esophagus problem, and you may need a chest x ray or other tests to be sure your esophagus is not perforated (rare but serious).
