Official title
Greater Occipital Nerve (GON) Block for Migraine
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Migraine and the skin sensitivity that accompanies it can go away in minutes after a nerve block, which is a procedure involving an injection of a small amount of a local anesthetic next to a nerve to the skin, causing an area of skin to become numb. We have also noticed that light sensitivity goes away quickly after a nerve block. We would like to see how quickly this happens and how long the benefit of nerve block lasts. We are interested to see if these effects are due to the injection itself or due to the lidocaine. A subject may be asked to participate in this study if a subjects physician has planned for a subject to receive an injection of BOTOX® in the area of the Greater Occipital Nerve (a spinal nerve located at the back of the head) as part of a subjects routine preventive treatment for migraine today.
