This clinical trial is focused on studying the effects of repeated corticosteroid injections for people suffering from chronic cluster headache. Chronic cluster headache is a severe type of headache that occurs in cyclical patterns or clusters. The treatment being tested involves injections around the Greater Occipital Nerve (GON) to help prevent these headaches. The study uses two types of injections: one with Depo-Medrone, which contains the active substance methylprednisolone acetate, and another with NaCl 0.9% B. Braun, which contains sodium chloride. Some participants will receive a placebo injection.
The purpose of the study is to determine if these injections can safely and effectively reduce the frequency of headache attacks over the long term. Participants will receive injections over a period of time and will be monitored to see how often they experience headaches, how severe the headaches are, and how long they last. The study will also look at the overall quality of life of participants and any side effects they may experience.
Throughout the study, participants will be asked about their experiences and whether they believe they received the actual treatment or a placebo. The study aims to provide valuable information on whether this treatment can be a convenient and cost-effective option for managing chronic cluster headaches.
