This is something new for me. I have been battling hypothyroid since 94 and my TSH levels have been sort of uncontrolled this past year, I'm thinking due to severe stress. In the past month or so I've noticed this occasional feeling in my throat, tight, like the throat muscle aches, or a lump. Causes me to want to swallow lots. Throat doesn't hurt though. There is occasional acid taste. Would this be reflux maybe from the stress??? I'm so sick of problems. I bought some OTC antacid, famotidine. Hope it works.
