What causes swollen lymph node in posterior cervical region?
Patient: I have a swollen lymph node in my posterior cervial region... A straight line from my jaw to about 1" behind my ear on the left side of my neck. It swells and goes down just about daily. In the morning its hard and maybe the size of a penny around but you can't see it threw my skin. Then in the afternoon it's barley there... I can still find it but its small, about the size of a pencil eraser around and I'm wondering what that could be from, maybe sleeping wrong? Also I'm a hypochondirac and I have 2 small children and don't get enough sleep. Could stress be a cause? My head itches a lot and has since I had my kids and I have hypothyroidism. I just don't know what to make of it and my doctor rolls her eyes every time I ask about it. THanks for you help! Doctor: hi thanks for posting on healthcaremagic.com after thoroughly reading about your concern, I concluded that swelling in region described could be of several reasons it could be possibly a throat and mouth infection, tuberculous, dermoid or thyroglossal cyst or related to your past history, in all cases it need to be proper examined  and investigated by a competent physician which can help you out with proper history of your disease.thanks and take care.Dr Jawad Alam
