I developed a swollen lymph node in my neck area under my left ear about three weeks ago. It grew quickly overnight, but then came down dramatically after taking antibiotics for ten days. It has gone down quite significantly and keeps going down every day...I cannot see it anymore, but I can feel a small swollen area under my skin. Went to the the ENT doctor two days ago and all checked out fine...no cancer in tonsils, mouth, vocal cords, throat, etc. But they want to do an excissional biopsy to remove the lymph node and check it for cancer. Makes sense? Also, I am taking pantoprazole, simvastatin, lisinopril, amlodipine and coreg...could any of these medications have caused the swollen lymph node?
