I do find that any change in the barometric pressure affects my headaches..they get much worse. Ice and my yoga nidra tape seem to work the best for me. I agree with nightnurse about visualizing the pain leaving your body.

Please check out Yoga Nidra, if you are so inclined. There are short clips on YouTube and you can buy the relaxation tapes to guide yourself. It 's a great tool to help yourself, very easy and a wonderful way to destress and calm yourself. The military has been using Yoga Nidra for PTSD in a program called IRest since 2006.
