Chiropractic methods employ a holistic approach to pain relief through massage, spinal manipulation and periodic adjustment of joints and soft tissue. Though many who suffer from Migraine are unable to find relief with chiropractic treatment, some have quite positive results. I think you should explore all non-drug options openmindedly. If you enjoy positive results, stick with what you're doing, if not, then maybe it's time to move on.
There are several studies that also show promise. Take a look at the follow example:

One hundred and twenty-seven migraine patients (at least one migraine per month) were divided into two groups for comparison.

• Group 1 received chiropractic adjustments at specific vertebral subluxations determined by the treating practitioner
• Group 2 served as controls and received inactive treatment (electrical stimulation with no current delivered).

Subjects receiving chiropractic adjustments reported substantial improvement. They had fewer migraines, shorter durations in migraines, less disability and lower use of medication for their migraines following two months of treatment. One in five participants reported a 90% reduction in migraines, and half reported a significant decrease in the severity of their migraines.

If you're tired of:

• Migraine headaches ruining your day
• Conventional over-the-counter medications proving less than effective
• Conventional over-the-counter medications being often accompanied by dangerous side effects

Try to fight the pain from another angle. To find out more about the potential benefits of chiropractic care, schedule an appointment with your doctor of chiropractic.
