Wow, that's an awful situation to be in, especially since you know you're right. I do think ER is a viable option. It's always a gamble as to whether or not you will get a good team once you are there, but if you go armed with your prescription bottles, and literature, that should help. Personally, I have never had a problem with ER and I live in a rural town that doesn't see much of anything other than oldies, kids with ear infections and folks with farm injuries.

You seem very aware of the importance of breathing and swallowing, which is good. It sounds obvious, but many people get themselves into trouble by waiting to see if things improve. Trust your gut when you feel things are getting out of your comfort zone. At that point, head to ER.

Best of luck to you.
