Yes, I have used bio-feedback with good results. I also use:
meditation, relaxation/guided visualization audio, self hypnosis,
hypnosis, crying, cursing, stomping around the house, whining and taking
meds.
I have a full bag of tricks that I go through each and every time the
pain gets to be too much to bear, and daily rituals that just keep me on
an even keel. I love http://www.brainsync.com audio - Kelly Howell's voice
soothes me and the binural beats technology used in brain sync audio is
the finest I have found, so far. I download MPs to itunes and upload to
my ipod. I am fascinated by the brain/bio connection. I highly
recommend Brain Sync, but there are plenty of sites that offer hypnosis
cds and MP3 for relaxation and pain management.
My latest weapon against pain is playing Bejeweled 2 on my iPod touch
while listening to my favorite playlist. Music and mindless games are
keeping me sane these days.
Try it all! If there was ANY one thing that worked we would all be using
it - I think that we all need our own bag of tricks, and just reach into
it and try one things and then another. At the very least, you will
pass some time and give yourself something to think about other than
pain.
