Hi, when my little boy was around 8 months old we noticed a small lump at the back of his skull, near the bottom of his hairline behind his right ear. We went to the doctors and a trainee GP said that it could just be a swollen lymp node and said to go back if it ever got bigger or we noticed more. It's never got any bigger and just stayed the same size really and he's now 20 months. I went to the pharmacist the other day and they checked it over and said for peace of mind go back to the doctors and get it checked as it's slightly hard (I think) and I'm not too sure if it's moving or if it's just the skin over the top moving. I rang the doctors back yesterday and they said it doesn't seem concerning as it had got bigger but he's going to check over it on Monday. I suffer really bad with health anxiety and now worrying something's wrong because it's never shrunk.
