The present disclosure generally relates to a system for treating headaches and other pain associated with the occipital nerves. More particularly, the disclosure relates to a system of treating pain by selectively activating specific nerve fibers with a single, fault-resistant contact situated proximate to, but not in direct contact with, portions of one or more the occipital nerves. Additional measures ensure the lead does not migrate or fracture, resulting in long-lasting pain relief.
