Seasonal allergies (& chemicals) cause face to swell under chin and around jawline, painful and uncomfortable. with neck pain. doctor didn't help.

Contact dermatitis?: Your seasonal allergies are airborne, so would hit primarily moist mucous membranes (eyeballs, inside nose, palate and lungs); would not normally affect intact skin of face, chin, angle of jaw. I have seen extremely high pollen re-erupt childhood eczema on back neck and folds arms legs. Have u considered chemicals in sunscreen or other products causing contact dermatitis? Dermatologist visit?
