If it is allergic you would also wheeze as your throat constricted. You would feel it down into your lungs. Try Claratin D and see if that clears things up. It is over the counter here. Another thing to try is Benedryl which is the first thing they would give you for a allergic reaction that is mild. A severe reaction and you would have trouble breathing in minutes. Do your eyes water? Do you also experience headache along with it?
