Hey Kalni-- I'm sorry to hear that you're having back problems!! whoever suggested EFT I also recommend it. It is really easy to learn, there is a great demonstration at http://www.tapping.com/ plus the guy has a cute british accent.
Another awesome way to heal yourself is anusara yoga. basically you can fix anything by putting yourself back into alignment. there are a bunch of free classes up (and they post new ones all the time) at http://www.yogatoday.com. Neesha Zollinger is the anusara yoga teacher... the same style I do.
