My husband has had a lump on the right side of his neck just below his jaw, for several months now.  He was told it was coming from his tooth that needed to come out.  He got the tooth removed, but now the lump is still there and when he eats, you can actually see the lump expanding??  Is this a plugged saliva gland?  He had a stone in his saliva gland on the other side of his neck many years ago that he had to have removed, but this is not acting exactly like that one did.
Hi, From history it seems that your husband might have some problem with salivary gland. There might be having infection in salivary duct or stone giving rise to blockage and resulting collection of saliva in salivary gland as block does not allow saliva to come out. Consult oral surgeon and get examined. Ok and take care.
