A clinic in Los Angeles offers a range of treatments for migraines, stress and high blood pressure, from drugs to biofeedback therapy. This painless, drug-free therapy is one of the newer therapies on offer for migraine and tension headache sufferers. It monitors bodily functions like heart rate, blood pressure and muscle tension. Research has shown that by monitoring them and feeding them back to the patient, the patient can gain voluntary control of them. So by knowing that you are tensing muscles and have high blood pressure, you can start finding ways to release the tension and lower blood pressure, for example, and the pain can be relieved.
