I found a pea sized lump about 8 months ago on the right side of my neck. I went to the doctors 3 months ago and he said he couldn't feel anything. I've noticed it's gotten very slightly bigger and a couple of friends said they can feel it and see it when I tip my head slightly. I've also noticed I'm very itchy everywhere and I'm not sleeping well. I don't no if that's related? I want to go back to the doctors but it is very small and it put me off last time. Any advice would help. Thank you.
