My 10 yr. old son has been constantly clearing his throat for what seems like forever. He does not have any signs of a cold, sinus infection, allergies or anything of the sort. He's the picture of health. He does have what appears to me to be an elongated uvula (drags the back of his tongue) but he says it feels like he has something in the back of his throat that needs coughed up. Nothing ever does come up and he has no nasal drip. I've looked at his throat and everything looks good. Nothing swollen. Could this just be from his uvula? Should I take him to an ENT? Our doctor just brushed it off last time I mentioned it. I really don't think it's good for his throat to be coughing and clearing it constantly for so long. He doesn't have a sore throat either but I figure if he keeps it up he will before long. It's starting to really drive the rest of us nuts too. Any ideas?
