Over 13 years of chiropractic practice, I've seen a lot of patients who suffer from migraines.  They can be incredibly difficult to get rid of with conventional medical treatments, which basically amount to medications to either prevent them from occurring or reducing them when they appear.  Both of these options are only covering up the symptom of pain, instead of actually getting to the root of the problem.  Unfortunately, these medications have such a long list of side effects it would take me a full page to list them.
