Anyone else developed a sudden weird reaction ONLY to beer? Upper back pain & lump in throat

Hey everyone, looking to see if anyone has gone through something similar or knows what this could be.

For over a year now, I haven’t been able to drink beer at all. Before this, I drank it totally fine with no issues.

It started on a trip where I had a “bromosa” (beer with orange juice, I know, super corny lol). Right after, I got hit with intense upper back pain—especially when taking a deep breath—and this really uncomfortable “lump in my throat” feeling. It was the first time it ever happened, so I just assumed I was exhausted from traveling. I actually drank Busch Lights the rest of that trip and was fine.

When I got home, I had a beer again and the exact same thing happened. That’s when I realized it was the beer. Now even over a year after the first reaction I can’t even finish half a light beer without triggering it.

The weirdest part is that it’s only beer. Seltzers and liquor don’t bother me at all.

I’m not a big beer drinker to begin with (it’s pretty few and far between, usually just if it’s what’s around at an event), but it’s weird how this just started out of nowhere. Since seltzers and liquor are fine, I’m guessing it’s not the alcohol itself, but maybe something specific to beer like hops, yeast, barley, or histamines? Or maybe some weird esophageal spasm/reflux trigger?

Anyone else experienced this or have any idea what it might be? It will completely take me out of commission, lying on the floor in pain
