Hi all -- I recently tried a 2.5 minute cryotherapy session (-160 degrees F) on a whim while visiting my daughter. Well. I walked out of there feeling better than I have in years! I've always responded well to cold therapy like ice packs but this was whole body immersion... granted I did not have a migraine before I went in, but I felt really good afterwards and migraine activity was really low for days following. I didn't even get a migraine during the 10 hour drive home in horrible rain storms. I am thinking this could be a nice addition to the treatment pie. Anyone else ever try it?
