Thank you everyone for replying.
To answer a couple of your questions, no, I don't have thyroid trouble. I have had 9 psych admissions, and each time they did tests to see if there were thyroid issues (standard test for everyone) and my tests always came back fine.
As for acid reflux, I'm not sure if that makes sense for me. I only drink water, nothing acidic like soda (not even coffee, no alcohol). Also, I have a clean and healthy diet, no junk food. I'm actually slightly underweight, so I don't think acid reflux makes much sense for me!
Today the left side of my throat still hurts quite a bit, but the uncomfortable feeling when inhaling has gotten significantly better. I'm hoping this will just be a temporary issue.
