Occipital nerves allow us to feel sensations in the scalp. An occipital nerve block is done to decrease headache pain, caused by migraine, injury (concussion), muscle tightness or occipital neuralgia. The medicine used is either a local anesthetic or a combination of a local anesthetic and a steroid. The medicine is placed around the occipital nerves, which are located just beneath the skin, in the back of the head. The occipital block is usually done in the office.
