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!
