The answer to this question is not a simple one. You see, as I mentioned above, if the cause of your headache is due to muscle trigger points (or if they are a contributing factor to your headache) then trigger point therapy is the answer. However, if your headache is due to other factors in addition to trigger points, for example high blood pressure or hormonal changes to name a few, then trigger point therapy will remove the muscle tension but will not completely resolve the headache because the other underlying causes are not being addressed. This is why if your headaches persist or you're not sure what is causing your headache, you should see a qualified doctor or healthcare provider.
