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.
Usually, a sore throat caused by a run of the mill virus like a cold wouldn't cause the swollen tongue, swollen lymph nodes but could cause the slight ear and throat problems. But Strep throat can cause serious problems so since you had it a couple of times in addition to the swollen lymph nodes I would see the ENT.
