The patient is kept conscious for the duration of the procedure. A small gauge needle is inserted at points of the greater and lesser<unk>  nerves down to the periosteum of the occiput. Some pain may be felt during the insertion of the needle through the skin. Injected anesthetics give pain relief almost immediately while steroid injections take 3-5 days to provide relief. The procedure has no major common complications, but some uncommon risks include bleeding, especially if on blood thinning medication, infection, and nerve damage.
