I was sitting at my desk today and put my hands up to my neck to I noticed what felt like a swelling down the right side of my neck. It is down from behind the ear inbetween the back and side of neck. on close inspection in the mirror it is a very sizeable swelling. It feels and looks like a large roundish lump almost in the area of the glands around the neck. There is no pain or tenderness and because I have long hair it is not normally noticeable until I lift my hair up. I have looked around the internet and am fearing the worst. I dont really have any other symptons. I am a 50 year old quite well woman. No loss of appetite or anything until now with the upset of finding this. I am going through the menapause and experiencing night sweats and hot flushes etc. What could this lump be?
