Hi there -
What color are they? I am glad you are seeing your doc quickly.

I haven't had this, but if they are not colored, and hard, maybe they are glands. I get a hard, pea-sized lump in my neck when I am stressed, or tired, or sick. I panicked, ran to the doctor, and he said its just a gland/lymph node, and if it goes away, its fine. It will stay hard for a few days, then go away. If it is really red, or white, it might be something else. Good luck.
