I have a swollen lymph node behind my right ear I noticed it m about two months ago and it hurts to begin with a tiny bit at the time I had a sore throat's and a banging headache for awhile it all calmed down but then it stops and it wasn't painful it went down after a few weeks but before I knew it was back again it feels hard and fixed in place but sometimes it feels a bit squidgy where I can press down and it feels like my finger is falling between two lumps just a small gap does anyone have any idea what this could be thank you
