Hey Teresa,
I didn't really put much stock in neuro/biofeedback until I realized how very much stress impacted my RSD. I ALWAYS get attacks during finals time (I'm a senior in college), and even watching a thriller can increase my pain.

Personally, I find biofeedback techniques to be very beneficial. I'm not very good at recognizing the onset of stress, so I don't always start my relaxation soon enough to provide relief, but if you can learn to really recognize the onset of stress, it can work wonders.

My relaxation technique was developed with the help of a massage therapist (not the normal technique, I imagine) - it's a combination of yoga breathing and a slow, measured release of muscle tension - again, modeled on yoga techniques. I'm told that a variety of relaxation techniques are effective, and in many cases, it doesn't have to be completely physical - i.e. more mental than physical relaxation, since these are linked.

Regardless of your feelings on the subject, it can't hurt to try - this isn't like a surgery that could have bad side effects. It's important to have an open midn though, and be willing to make a concerted effort - it can be difficult skill to master, but the results can be incredible.

Good luck!
