Sometimes a lump is just a lump.

Ambra, you've already taken positive steps, like coming here, and planning to talk to your neurologist friend. It couldn't hurt to try to get your appointment moved up especially if it can relieve some of the anxiety of waiting. Just waiting and worrying about anything is a definite crazy-maker. Tell them this if/when you call about possibly moving up your appointment. People cancel appointments all the time so they might be able to fit you in someplace. Things to get better. So keep moving and taking positive steps.
