Migraines: Chronic migraines could be due to improper use of pain medications. Medication overuse headache can lead to frequent headaches. inability to identify triggers is also a possibility. Botulinum chemodenervation has been approved for treatment of frequent migraines more than 14 days a month. Occipital/supra orbital nerve stimulator may be effective. Consult your MD for diagnosis and proper treatment.
