Your focusing on the task and the pain from the thumb thieve your attention away from whatever else is bothering you. Also, the pain may release endogenous opiates that decrease your sensation of headache. Finally, there's also the placebo effect.
I wouldn't put much reliance into it. It's like my mother telling me things such as if my son is hiccuping it means he's growing, and to move his arm up and down approaching an old-time water pump when he's choking.

Sometimes I think that if someone does action X and unrelateecstaticlem Y goes away, they attribute X to curing Y. Source(s): heard several strange old wives' tale growing up and with my son
Well like you said it's acupuncture. Well it's kind knotty to explain but its kind a old types of remedy. Because rumors has it that once you fix nerves on you body you can performs some kind of instant healing. Well this moder daytime acupuncture is still popular but still I think this practice is not that yet proven as a medicine of this modern age.
it makes your stomach hurt less because you thumb hurts too, therefore your thinking something like your thumb not your stomach pains
