That's similar to my experience. I can get some tension-related headaches to go away by relaxing certain pressure points, which can be done either mentally, manually by massage, or by stretching certain face muscles and the muscles in the neck and shoulders. However, this works better for certain types of headaches than others. If there's a major fluid build-up in the sinuses, I may have to clear that up by eating hot-pepper salsa or something like that, or by making sure I don't sleep in a position that the fluid builds up on one side of my head (for me it tends to drain to the right side, so sometimes I have to offset that by sleeping on my left side). Also, if I miss a lot of sleep I will eventually get a migraine no matter what I do, and even migraine aspirin won't help until I catch up on my sleep. So it depends; but some kinds will go away by relaxing, I find. Some things that help me are: flexing my shoulders and neck in various directions, moving my eyes around in different directions, yawning, and massaging certain points like the top of the skull, base of the skull, under the center of the eyebrow ridge, between the eyes at the top of the nose, the temples, and wiping my palms across my forehead horizontally and then vertically up and down my face like I'm rubbing my cheeks into a smile--smiling helps relax the face muscles :-)
