I have this lump of a considerable size below my left rib cage, which does not compress, but moves sideways when pressed hard. I experience some kind of weight in that area while i am breathing, or i can feel something there while i am constantly sneezing which lasts for a day or two. Its not cold or fever which causes sneezing. my question is, What could be that lump below my left rib cage And why do i get constant sneezing when i dont have cold or fever, it usually happens anywhere or any point of the day, so i rule out allergy thing. please help me out
