I often get a week or two of tension headaches whenever I make any sort of huge change in my life. Like right now at 11 days sober for instance. Nothing pharmaceutical helps, so I have to just minimize the pain with relaxation and staying hydrated. I find that with tension hadaches, I tend to clench my jaw, which just makes the headache worse. If I can be mindful of my muscle tension, particularly my jaw and my shoulders, the pain is minimal. Doing a five minute body scan meditation can do wonders for a tension headache. My doctor told me that lying on your stomach with your arms crossed under your chest helps regulate circulation and cuts down on the throbbing. It seems to work sometimes, but it may also just be the power of suggestion. Good luck with your headaches. And hey, it's still better than a hangover or withdrawal!
