Here's one -
No specific intra-cerebral target associated -- I suppose results do vary.
(Did this to a checker in local store, (no customers left) who was mumbling about pain.. pain.. Asked her if she wanted to try a non-pharm-chem approach, which sometimes just Works. She signed the release.)
This assumes at least normal hand-strength. Unclear yet.. if some steroided-out biped might do actual harm, but the skull is Very strong, except to pointy things+physics:
You lace fingers over top of head. With palms, you try-to 'crush' the skull from the sides [see above]. Seems best position to face the person, but might be OK from back. Best to slowly apply pressure up to your max strength -- then sustain that, until your hands go all wobbly. That's rarely as much as a minute.
Then, very-gradually: you reduce pressure.
Needn't wait long for results. In case above, ~ 10 sec later she said, It's Gone!
(Maybe now she prays to me.. who knows..)
In any event: it can't hoit, unless you're a mutant (nor has anyone found the pressure to be unpleasant.)
(You can almost.. do this to yourself. I get v. few headaches, but seem to recall once, doing the drill; quite less effective at that angle, of course - think it worked.)

Ed: One theory is, that the 'tectonic plate-like' skull bones which are supposed to permanently fuse during infancy - sometimes do a Microsoft-grade job, and this causes certain local pressures - which may manifest as that loose-term, 'headache'. At least this makes a certain physics sense. We may be sure that no pharmchem-funded U. or bizness will make many tests of the phenom - HFT could you Patent it?
