9 out of 10 Americans suffer from headaches. Some are occasional, some are frequent, some are dull and throbbing, and some can cause debilitating pain and nausea. Research shows that spinal manipulation -- provided by chiropractors, such as Dr. Blitz, may be an effective treatment for migraine and tension headaches and headaches that originate in the neck. Spinal manipulation results in almost immediate improvement for these headaches without side effects and with long lasting relief without the need for prescription medication.
