First let me say I went to my pcp and am scheduled for an esophagram day after tomorrow.
I am a 38 year old female and about 4 weeks ago I started feeling like there was a lump inside my throat. It's about 2 fingers above that dip where your neck meets your chest, I think right below where an Adam's apple would be, in the thyroid region. Nothing is palpable but swallowing has become awful - not painful, but incredibly uncomfortable. I don't think it is necessarily interfering with my ability to swallow but since there is a constant feeling like something is there, I find myself swallowing repeatedly. Originally I though maybe post nasal drip, then I thought reflux but the strangest part is that when lying flat on my back I can barely feel it. When I lay on my side or am standing up it comes right back. That kinda goes against reflux and nasal drip which both are usually worse when lying down.
I am now stressing about thyroid or throat cancer and was wondering if this was a common symptom. What would cause it to feel better when lying down? I'm assuming (without much anatomical knowledge of the neck region) that when laying down, the esophagus and trachea shift back and there's more room so whatever the lump is on is not pressing against the other structures. Does that sound possible or likely??
