Which lymph nodes are swollen can help identify the problem. 1  The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat.  Glands in the armpit (axillary lymph nodes) may swell from an injury or infection to the arm or hand.
Seasonal allergies do not directly cause swollen lymph nodes. However, seasonal allergies may cause sinus infections or ear infections, and these infections are a frequent cause of swollen lymph nodes in the neck. Swollen lymph nodes can be due to a number of other conditions as well. If your swollen lymph nodes persist or concern you, see your doctor.
