Maybe (not) . . .: Urinary tract infections do not cause swollen lymph nodes, especially not so distant as the back of one's head. While this lump could represent a lymph node, it could also be an infected cyst or folliculitis. Since it's painful, please go see your Family Doc for evaluation & appropriate treatment. In the meantime, finish your antibiotics.
