I don't think it does. You probably just went into caffeine withdrawal which caused the headache. Consuming caffeine then makes the headache go away.

It definitely does. Not that you're wrong about withdrawal causing it as well, but caffeine is often prescribed for head aches after certain surgeries.

I was told to buy over the counter STAY AWAKE trucker pills after a spinal tap to help with the terrible head aches, and it worked! I think it has something to do with relaxing your blood vessels, similar to nitroglycerin with angina.

A headache could be your body dumping something like salt/heavy metals out of your brain. When you drink the coffee your body has to deal with this and it is just stopping this "detox"

Yeah this is probably what's happening in most cases, but I do recall reading somewhere that caffeine increases the efficacy of some painkillers, like ibuprofen or acetaminophen. That could also be bullshit like most things you read are.

Maybe it's just that caffeine makes you feel great in general, lol

It improves the effectiveness of aspirin. Some aspirin preparations like powders also contain some caffeine.

Goodys is on the list.

Because you are addicted to caffeine.

It's a vasoconstricter

This is the correct answer. Caffeine causes blood vessels to contract, which helps with some headaches. In fact, it’s an ingredient in certain headache medicines.

It doesn’t work on all headaches, however, and it can actually cause headaches on its own in rare cases.

Because you pee the bed at night and you're the reason daddy hits mommy.

Idk but it's working this "morning"

It helps with nerve and joint pain, too.

I don't consume caffeine on a regular basis, but when I need to get things done like prep a house to sell I take Mr Hyde workout supplement. It doesn't give me energy but it sure takes the edge of pain and joint stiffness away.

I had a spinal tap done. They can cause fierce headaches. Dr. told me to take caffeine if I got a headache.

Next day I got a bad headache. One Diet Coke later…no headache.

I don’t know why caffeine works. But it did for me.

Stop drinking diet soda. It is terrible for you.

Never fixed one of mine. Now combining a cup of coffee with aspirin potentiates the aspirin, which is why Anacin kicks aspirin's ass.
