Silent reflux (LPR) can cause this sensation. I had globus sensation, in addition to other symptoms such as constant throat clearing and post nasal drip, for years (but no heartburn so did not recognize this as acid reflux). No one ever diagnosed me with reflux and my endoscopies and laryngoscopies have always been clean with normal mucosa. Once I dropped all acid products (vinegar, citrus, hot sauce, tea, coffee, alcohol, fried food, carbonated beverages, processed foods containing any type of acid, tomato, onion and garlic - I also limited sugar, dairy, and gluten), all these symptoms went away after about 2 months on the diet. Unfortunately, I appear to have had enough damage from reflux that my upper esophageal sphincter is now not working properly (or it's a long covid symptom - my other theory). But diet won't fix the dysfunction so my ENT is going to try Botox to the upper sphincter muscle (cricopharyngeal muscle). At any rate, diet is always worth a shot (but you have to do it for at least 6 weeks to 2 months, it's not a short-term fix, and then you have to be mindful thereafter). Hope you find some relief.
