Experts aren't entirely sure how biofeedback works. But if biofeedback is successful for you, it may help you control symptoms of your condition or reduce the amount of medication you take. Eventually, you can practice the biofeedback techniques you learn on your own. You may need to continue with standard treatment for your condition, though.

On the downside, learning biofeedback can take a lot of time and, if it's not covered by your health insurance, it can be personally expensive. In some cases, biofeedback may be no more effective than other simpler, less expensive relaxation techniques, such as yoga.
