This sounds like a case where getting a medical opinion makes sense. You're in the US so cost could be a factor, but checking it out would be safer. My guess is the food scraped the esophageal lining and left it inflamed and irritated, possibly with some muscle spasm making swallowing difficult. The main reason to see a doctor is the small chance of a tear that could lead to infection or bleeding. Otherwise stick to liquids and soft foods while it settles. Even a low chance of something serious is enough reason to get checked. Most likely they'll just watch it, but a doctor is less likely to miss anything, or they might do a scope to see exactly what's happening. Skipping the retatrutide dose for a few days shouldn't hurt.
New to the forum and not sure this is the right spot, but hoping others have had something similar. Started retatrutide five weeks ago and the first four went smoothly until January 6 when a large piece of meat got lodged in my chest for hours. Since then swallowing has been inconsistent with tightness and a dry lump feeling in the throat. Meat is now impossible to eat. I already have GERD and take a PPI daily, recently upped to two 15 mg lansoprazole plus famotidine at night. Saw a couple mentions of Flonase helping. Not sure if anxiety, the medication, the choking episode, or everything together caused extra inflammation. Holding off on my usual 1 mg weekly dose today because I'm worried.
