Cluster headaches are a rare but severely painful neurological condition, characterized by intense, burning attacks that occur in cyclical patterns. Often striking like "clockwork" at night, they cause one-sided eye pain, restlessness, and autonomic symptoms. While their cause is unknown, effective treatments like oxygen therapy and prescription injections can provide life-changing relief.
