I've never had this before but just recently I've had a horrible feeling of something large stuck in my throat/esophagus. Before it felt like it was upper now it went down and it's painful when I swallow. I used to have awful acid reflux and this time it happened when I ate gluten and maybe that's what did it? Thankfully I'm going to see a GI in a couple weeks and then get an endoscopy. I hate this feeling and pray it goes away. Has anyone with CFS had throat problems?
