GiGi, I suffer from the same problem lately too. CMA's Advice is very good. Lots of water, breathing exercises, and not being hard on yourself if you need to take a painkiller to help you function. Something else that I do that works really well is to sit down with a headache and actually talk to it and invite it to come in and take over. By being really present with it and not trying to push it away through resistance, I notice that the pain loses its power and very often times goes away. Your immediate feelings will be fear of doing that because you do feel like you will be swallowed up by the pain but if you can sit and be present with it- relax into the headache-it will start to shift. Give yourself plenty of time to be with the headache and make sure there are no distractions. Also having a dialogue with your headache works really well too. I like to write out dialogue rather than talk it out loud, but either one would work. Talk to your headache and ask it why it is there and then give it a chance to respond. I always seem to find that when I put a voice to those different parts or different pains, they are not actually trying to harm me, which makes sense because the basis of TMS is that the mind is trying to divert your attention from feeling emotions. Maybe your headache will have a chance to let you know what it's trying to protect you from. Doing this helps me to see the pain not as the enemy, but as a friend who is trying to help me but isn't doing it in a way that is working for me. Seeing the pain as more of a friend helps me to relax into it, which I think also helps it to go away.
Hope things start feeling better.
