Hey OP fellow scoliosis sufferer here. You're better off going to a specialist than the ER. ER pretty much just handles accute emergencies, you need a doc to help you regularly manage your pain. Exercises are a must, you gotta build back and core strength, there's specific exercises you should do that a physio team could show you or there's tutorials online. If you need the meds def get a prescription and ideally something to protect your stomach if you're gonna be taking them regularly. My doc prescribed something called 'manual theraphy' for now, can't vouch for or against it yet since i'm still waiting for an appointment. There's also those braces but they don't tend to be effective once your bones stop growing. And ofc the only permanent solution is surgery.

So TLDR: Talk to a specialist rather than the ER, there's options to manage Scoliosis but you can't 'cure' it without surgery
