I have had this hard lump on my posterior pharyngeal wall for some time now. Sometimes I can feel it regularly and it makes me vomit just because it constantly feels like there is something stuck in my throat. And I ve just realized the last year that I can actaully feel it with my finger, it almost hurts to touch it. It goes away for a month or two at a time but always comes back. I have seen an ent and done a swallow barium test, both times when my throat was not bothering me tho but this is the only time they could get me in. And I ve been told it s all in my head. Like I said tho now I ve actaully put my finger in there and I can feel a lump so I know I m not crazy! Anyways this has been going on for 2 year s in may. Any advice would be great!
