My son is 11 and for a few years now, he complains that he has so much flem in his throat that he can't swallow it and is constantly spitting it out. It is to the point that it is happening all day every day! His doctor says that just take allergy medicine, but it doesn't help! Could taking Lactaid help in someone with this problem. He is already drinking Lactaid but if it is a food allergy then what would be next. Please help me, because I really can't take the hucking up flem any more!

Thank you!
