When i am up and walking around i feel fine when i sit or lay down i get a headache thats when i have more time to think about a headache am i giving myself a headache?

I think it's : Psychological. Check your blood pressure (normally below 130/80) go see your dr if headache gets worse.Stay active, relax, do deep breathing, get enough rest. (same thing with me, I have all the aches and pains but they all disappear when i play golf!) do the things that u love to do. That relaxes your mind. Look at lovely imagery and watch comedy!
