I've had at least two swollen gland up consistently for three years now. One behind my ear and the other back of neck just below my hair. These have been there for three years even though I am not ill. Should I be concerned? There are other things to but I fear I am being silly, I've had others on the bottom of my head appear and now where that is on my head and back of neck I find the skin itchy. So like I'm scratching the back low of my head near where the glands are and like a liquid comes out. Plus don't know if it's relevant I find that every so often my skin feels itchy like underneath my skin in my arms and breasts. Also have a pain every so often in my breasts/chest, I've had feelings of breathlessness.
