I have to clear my throat constantly it gets worse after eat. My voice gets very hoarse at times from clearing/coughing my throat. It's been going on for 8 months and it's driving me nuts.When I lay down to go to sleep it totally goes away when I get up the clearing of the throat begins again. I've seen a lung specialist, an allergist, an ENT, I've had a chest x-ray, an upper GI series all normal. Anybody out there that can help me. I'm at the end of my rope.
