Anesthetic greater occipital nerve (GON) blockade is a simple, inexpensive, and safe procedure that has demonstrable headache pain suppressing effects. In this study, Veterans with post-traumatic headache will be randomized to receive 0.0%, 0.05%, or 0.5% bupivacaine in bilateral GON blocks and the lasting (i.e., transitional) effects on headache frequency measured in a headache diary.
