Yes, you should be seen by a doctor. I'm assuming it's in the front of your neck, and my first thought was lymph nodes. I understand you're scared, but guessing about it won't fix whatever the problem is and if it IS something serious early treatment often can completely cure the problem. The longer you wait the more it can fester and get worse.
