Objective: To evaluate the effect of GONB, with or without trigger point injection (TPI), on dynamical mechanical (brush) allodynia (BA) and on head pain in migraine.
Background: Patients with migraine often have cutaneous allodynia, which is related to sensitization of central pain neurons. Greater occipital nerve block (GONB) is an effective treatment for migraine headache, however its effect on cutaneous allodynia in migraine is unknown.
Methods: We studied patients with migraine and BA who were treated with GONB with or without TPI. Demographic data, migraine history and headache features were documented. Allodynia was evaluated using a structured …

Cutaneous allodynia is defined as the perception of pain when a non-noxious stimulus is applied to normal skin. This phenomenon has been demonstrated in migraine patients during an acute attack. It is thought to result from central sensitization of neurons in the trigemino-vascular system and may spread to areas beyond that of the referred head pain.
In a recent study, migraine patients demonstrated increased temporal summation to painful mechanical stimuli in their referred head pain area between attacks. This suggests that changes in physiologic properties of nociceptive neurons may occur in migraine patients between attacks.
We describe a migraine patient …
