The label on a can of Red Bull explicitly states that mixing it with alcohol isn't recommended (it’s worth actually reading the fine print; those warnings aren't just decorative), and I suspect the manufacturers at Red Bull know exactly why they included it.
I’m certainly no expert in biochemistry, but my hunch is that it comes down to the high caffeine content in Red Bull acting as a stimulant. Alcohol, conversely, acts as a depressant, which creates a conflicting interaction within the body.
Brenda Scott14, in your case, it was likely that the alcohol caused some muscle relaxation—potentially including the heart muscle—while the Red Bull was simultaneously forcing your system to ramp up. That kind of physiological tug-of-war could easily trigger pain. It's similar to what happens when people experiment too heavily with substances that have opposing effects.
Again, I’m not a doctor or a biochemist, so if anyone with actual expertise wants to correct me, please do...
