Hi There, My Name Is Angela. I Have A Supraclavicular

Hi there, my name is Angela. I have a supraclavicular swelling over 6 moths in both side of my neck left one bigger than the right one. sometimes I feel a burning paind on my left one and pressure on them. I dont know what I have but I had visited my primary MD and he told me that is a fat tissue. It is so uncomfortable I dont know what to do or who I should be visit for better look. thank you so much.
