Surely you know someone who has the language skills to help you at the hospital? If not, you can wing it with hand motions, like point to where it hurts. If you are at a hospital, they will treat the symptoms medically regardless of the words you use. I'm sure there is someone at any hospital who can translate. They check vitals and treat accordingly, just like with any patient.
I think if you make it past three days you've passed the worst of it. It takes 72 hours to go through the dangerous part of withdrawal. Why don't you have a friend come sit with you/spend the night for two days?
I was drinking a lot at the end and I tapered a bit, my withdrawal was unpleasant but that is the only word I can use honestly. Of course that said, I was probably just lucky.
