My 14 yr old son has for sometime had difficulties when eating various types of food, ie., chicken, rice, apples, bread and grapes. He says he gets a sensation in his throat, his saliva becomes very sticky almost like mucus, and has difficulty in swallowing and breathing. He beomes very scared as he says it s difficult to breathe. This does not occur every time he eats, only occasionally. I have seen my GP who referred him to a speech therapist, who was unable to help.
