A member asked:
My son will be 10 months tomorrow and he has a bump or knot on the back of his head, i don't know how long its been there, can teething cause a bump?

No: Teething only affects the gums in the mouth. The knot on the back of his head is probably the result of bumping his head.

Likely a lymph node: There are thousands of lymph node located around the body that help screen out germs in the body serum before it returns to the circulation. There are many in the neck, head and behind the ear. At rest these are often 1/4 inch in diameter and may grow to marble sized when reacting to a stimulus. Bug bites, or viral infections can increase their size.
