It's been about 3 months since I've noticed a lump on the back, right side of my neck. It's about the size of a small gumball. I first noticed a sore pimple like thing and that was to the left (NOT on top of) of the gumball sized lump. At first, the pimple thing wouldn't pop but it did eventually and has since almost fully went away. However, the gumball lump is still there and I can't tell if it's grown or not. It doesn't hurt at all, acutally is starting to become almost numb. I'm debating on going to the doctors or not, and maybe someone has had this or could tell me what they thing it is? PLEASE! Thank you :-)
