Lymph nodes become swollen in response to illness, infection, or stress. Swollen lymph nodes are one sign that your lymphatic system is working to rid your body of the responsible agents. Swollen lymph glands in the head and neck are normally caused by illnesses such as: ear infection.
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.
