Alcohol can lead to stomach irritation. This isn't necessarily an allergic reaction, but it's a direct reaction to a toxin, of sorts. Alcohol, when it gets into the stomach, actually causes an increase in secretion of stomach acid…that increased secretion of stomach acid can cause tenderness and belly pain. The belly pain can be treated essentially by trying to neutralize the acid; you would use Tums, Rolaids or products like that. But over time, it can have a disastrous effect, if you continue drinking.
