My Fiancee Is Experiencing Pain And Some Slight Swelling At

My fiancee is experiencing pain and some slight swelling at the back of her head, just below her ear and to the left side. The place is very tender to the touch. She does suffer from migraines and in fact had one, I believe, just two or three days ago. I should add that she and I are under extreme stress due to a work problem (mine and partly hers) that has now spilled -- erupted, actually -- into our personal life.
