 Greater occipital nerve GON injection is a commonly performed diagnostic and therapeutic procedure in headache patients. GON blocks have been shown to be effective in the treatment of a variety of headaches including occipital neuralgia, migraine, vascular headache, cluster headache, cervicogenic headache, and post-concussive headache. Local anesthetic and steroids have been successfully used for diagnostic and or therapeutic nerve pain such as lumbar radicultis with great success. Dexamethasone is a water soluble steroid, when combined with local anesthetic; it may increase the analgesia of block duration relative to its pharmacokinetics. When compared to dexamethasone, triamcinolone, a particulate steroid has a slower onset time but may provide anti-inflammatory effects up to several weeks. Investigators want to investigate to see if there exists a difference in reported pain intensity using the particulate anti-inflammatory corticosteroid triamcinolone with bupivacaine which may provide a greater reduction in reported pain intensity relief may allow the patient to undergo fewer interventional procedures.
