I've had a swollen lymph node on one side of my neck since Thursday. It has gradually got painful and the pain is now radiating to the top of my head almost in a straight line - the pain is under my skin/or on the bone and it hurts to brush my hair or lie on that side. I don't have any sore throat and no other glands are swollen although under my arms feel slightly uncomfortable. I have random rushes of hotness (I've already had menopause 4 years ago) but I've not taken my temperature. Would you go to GP or wait it out?
