I learned this by googling
apparently 40% of people who get heart burn and acid reflux experience the lump in throat sensation.
I woke up this morning with the worst acid, I could feel it burning my throat, talk about pain! been a long while since I had it that bad.
every time I burped, I would get burning, pain and a squeezing sensation in my chest.
an hour later I had the lump in my throat sensation pretty bad, I drank milk to help protect my throat from the acid.
anyways the sensation has eased off, Now I'm also wondering if it's the heart burn that causes the squeezing sensation in my chest.
