Hi Ed,
My daughter was dropped in a college class and landed on the back of her head. She too had bad headaches...What really helped was acupuncture. We we at the Stanford Integrative Clinic and this was her first experience w/ acupuncture. The type they did there was a super quick release of her headaches/head pressure but the effects would only last a few days. (Note she really never had headaches before the PCS)

Because the drive from our house to Stanford was stressful in itself. We looked locally for a doctor. Dr Rozenn of Santa Cruz has been super. You might want to contact her office to find out what type of acupuncture she uses. My daughter swears by it.

In addition, I think Berkeleybrain here on the forum wrote about a migraine free diet his dr prescribed. I believe he went to UCSF in the City. I haven't read a review from him about his diet but maybe you could PM him and ask.

There is a lot of information on this forum describing how to figure out what triggers your headache.

FYI...My daughter is still making gains and she is 2.5 yrs out. Her headaches are few right now. It does get better.

My best,
