Thank You For Your Time. I Have A Small, Hard,

Thank you for your time. I have a small, hard, itchy lump on my neck. Probably around C5-6. It is about the size of a pea. It started out the size of a BB about 6 months ago. I mentioned it to my ob/gyn and she said it was nothing to worry about. What is the best choice for a 2nd opinion? My pcp or a dermatologist or another specialty?
