It's your call! It sounds like you're okay right now and don't need emergency medical attention. Go to ER if anything I mentioned earlier happens (vomiting blood, throat tightening so much it's restricting your airway, bloody stool etc). Your family doctor is a good person to see tomorrow and get you checked over before deciding if you need ER or not. Probably all you'll get is a course of prophylactic antibiotics (GPs love their abx lol), some painkillers and maybe some fancy fiber to eat/drink. The GP might get you a req for an xray just to make sure, or they might decide to wait. Some medical professionals are going to tell you to go to ER regardless just so they can cover their proverbial asses, but from what you've described you're okay!

If you want something lower key than the medicine on your own, add some honey to your tea! Honey is great! And some bulky fiber.
