A Dramatic Relief from Cluster Headache by Classic Bloodletting Acupuncture Evidenced by Thermography Analysis: A Case Report

Background: Cluster headache is a severe headache, which causes severe impairment in the quality of life of the patients. Here, we report a successful experience of relieving cluster headache by puncturing the superficial engorged venules of the ipsilateral leg. Case presentation: This 72-year-old female with severe refractory cluster headache came from the United States to Taiwan to search for alternative therapy. Her headache was characterized by excruciating, stabbing pain on the left head, primarily around the orbital area with extension to temporal and occipital area, and accompanied with left nasal obstruction. Based upon the classic acupuncture method, her headache was dramatically and totally relieved by puncture upon superficial engorged venules of ipsilateral leg. Conclusion: This case reminded us that classic bloodletting acupuncture could be an alternative strategy for cases with refractory cluster headache. Besides, the connection between leg engorged venules and head suggesting the existence of some novel reflex, worthy of investigation in the future.
