I had an allergy attack I'm assuming from the change of seasons. my symptoms consisted of dry cough headache but then it turned into a little cold. My symptoms were a cough with little mucus headache. I took Robitussin extra strength. I did have a day where my ears were bothering me. After my symptoms left I was left with my left ear feeling like pressure .I would tug on the ear lobe and feel better. But now I feel like my lymph node is swollen. Is this an infection
