This condition can lead to severe headache pain, and the study aims to explore a treatment method called a bilateral greater occipital nerve block. This involves using an injection to block pain signals in the nerves at the back of the head, which may help reduce headache pain.

The treatment being tested involves two main substances. The first is lidocaine hydrochloride, a local anesthetic that helps numb the area to reduce pain. The second is sodium chloride, commonly known as salt, which is used as a solvent to help deliver the lidocaine. Both substances are administered through a subcutaneous injection, which means they are injected just under the skin.

The purpose of the study is to determine how effective this nerve block treatment is in managing headache pain related to spontaneous subarachnoid hemorrhage. Participants in the study will receive the treatment and their headache pain will be monitored to see if there is a significant reduction in pain levels. The study will help understand if this approach can provide relief for those suffering from this type of headache.
