I took HALF a shot and have the most painful stomach bloat/inflammation I’ve ever had. Should I go to the ER?

For context, I have a history of stomach problems. After a shot, I typically get a gastritis flare up for about 20 mins that is literally a 12/10 on pain, bullets of sweat pour down my face, my stomach feels a burning sensation that’s strong enough to send me into a fetal position on the bathroom floor. I get this symptom within minutes of consumption.

Today I took half a shot of whiskey. Within about 20 mins, I felt a pain almost identical to the usual pain I feel but instead it felt more like a “bloat” type of pain. It felt like my stomach was spasming which I assumed was gas moving around? (Could be wrong). Tha pain was vague enough to not make me sweat, yet ever-so-consistently present.

To make matters worse, it has been almost 4 hours now and it seems to have not alleviated itself much. I had to go home from work(self employed) because I was having trouble functioning and I am still laying in my bed squirming around and grunting, even as I type this.

I don’t really know why I can’t alleviate symptoms and it’s putting a HUGE damper on my mental. If anyone could share any insight or experiences of their own, I would hugely appreciate it. This is my personal hell and I neeeed to be able to work!

Thank you so much if you read this far!

TLDR: stomach inflammation/bloat-type pain won’t go away after only half a shot of whiskey.
