Stimulators for the treatment of headache.

Sometimes our best pills, well-placed injections, and lifestyle modifications are not enough, and headaches persist without sufficient relief. In such cases, battery-charged, electrical, or magnetic stimulators may be considered. This is a review of the pros and cons of such treatment, including the types of headache for which this treatment might be appropriate. Stimulators do not usually eliminate pain, but they can sometimes modulate it, and this is why this approach is referred to as neuromodulation for headache.
