My 8 year old son has been constantly clearing his throat for some time, I took him to the pediatrician last month, she precscribed a nasal mist for him, but it was not covered,(he doesnt want something up his nose either). Now he is complaining and crying because he says there is phlegm he cannot get out. It seems to be stuck in or around his throat. He is making barking noises and really trying to get it out. I dont know what to do for him at this point, any suggestions on what could be happening or causing this?
