My son takes 3 150 mg of Trileptal every night before bed. After aprox. 8 days, his lymph nodes behind his left ear started to swell. I took him to his family dr and they gave him an antibiotic. The pain went away but not the swelling. It has been about 15 days and now he has a swollen lymph node on the right side and the left hasn't went down yet. Is this the Trileptal and what do I do???
