It worked for me. I suffered from migraines accompanied by a chronic inflammatory desease. Was in a hospital twice every year.
Then I read a study about THC and bought these derivative pills they have in the Netherlands. When they are unavailable, a little bit of weak weed in a cookie will do the trick (search for recipes). But ONLY once a month. Treat it like very strong medication.
But the best thing (at least for me) was Tai-Chi. I have a warm-up manual that I do every day, I can post it here if you want. I have not slept in hospital sheets for 3 years.
