I experienced this out of seemingly no where about 3 years ago while in a 2 week nightly bible study group where we had food catered in every night. All of a sudden, I couldn't swallow so much as a sip of water, a bite of salad or any other food item. It would get stuck in my esophagus, and I'd have to run .to the bathroom to throw it up, as it blocked my airway. That lasted about a month over 3 years ago. It all of a sudden happened today when trying to eat some BBQ, I had to beeline to the bathroom to toss up my food, and any water I'd downed. Later on, I had no problems swallowing water or liquids, but as soon as I tried some of my leftovers, I had to run again. Any and all help or suggestions would be greatly appreciated. I don't have an issue with stomach acid or GERD.
