These studies suggest that right-sided headache pain can be associated with various conditions such as cluster headaches, SunCT syndrome, and occipital neuralgia, and may not have significant clinical implications in migraine diagnosis.

Headache Pain on Right Side of Head: Insights from Recent Research
Cluster Headaches and Right-Sided Pain
Prevalence and Characteristics of Right-Sided Cluster Headaches
Cluster headaches (CH) are known for their severe, unilateral pain, often accompanied by autonomic symptoms. A large Nordic multicenter study investigated the prevalence of right- and left-sided pain in CH patients. Among 383 patients, 14% experienced a shift in pain side, while the remaining 328 individuals showed no significant difference between right-sided (54%) and left-sided (46%) pain. This study challenges previous reports suggesting a predominance of right-sided pain in cluster headaches.
Case Studies Highlighting Right-Sided Cluster Headaches
Several case reports provide detailed accounts of right-sided cluster headaches. One case involved a 38-year-old man with severe right-sided headaches starting in the occiput and radiating to the face and upper teeth, with the most intense pain in the periorbital region. These headaches were accompanied by nasal congestion, lacrimation, and eyelid edema. Another case described a 70-year-old man with right-sided headaches extending from the forehead to the temporal region, accompanied by tearing, conjunctival injection, and rhinorrhea. These cases underscore the variability and intensity of right-sided cluster headaches.
Migraine and Right-Sided Pain
Clinical Presentation of Right-Sided Migraines
Migraines can also present with right-sided pain. A case study of a 62-year-old man described new headache attacks strictly confined to the right side, characterized by excruciating, pulsatile pain around and behind the right eye, often accompanied by ipsilateral lacrimation and conjunctival injection. This presentation highlights the potential for migraines to manifest with unilateral, right-sided pain.
Comparative Analysis of Right- and Left-Sided Migraines
An observational study examined the relationship between the side of migraine pain and healthcare use. Among 477 migraine patients, 47.9% reported right-sided pain, while 28.5% experienced left-sided pain. Contrary to expectations, there were no significant differences in psychiatric distress or healthcare use between patients with right-sided and left-sided migraines. This finding suggests that the side of migraine pain may not have significant clinical implications beyond diagnosis.
Secondary Causes of Right-Sided Headache Pain
Trigeminal Nerve Sheath Tumor
A case report detailed a 38-year-old man with right-sided headaches initially diagnosed as cluster headaches. Further investigation revealed a trigeminal nerve sheath tumor at the right trigeminal nerve root entry zone. This case emphasizes the importance of considering secondary causes when diagnosing unilateral headaches.
Vascular Malformation and SUNCT Syndrome
Another case involved a 70-year-old man with right-sided headaches associated with a vascular malformation in the right cerebellopontine angle. The headaches were characterized by short-lasting, intermittent pain with autonomic symptoms, consistent with SUNCT (Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing) syndrome. This highlights the need for thorough diagnostic evaluation in patients with atypical headache presentations.
Occipital Neuralgia Due to Schwannoma
A 38-year-old man presented with chronic right-sided occipital pain, later diagnosed as occipital neuralgia caused by a schwannoma of the greater occipital nerve. The pain was sharp, shooting, and aggravated by certain positions. This case illustrates that structural abnormalities can also lead to right-sided headache pain.
Conclusion
Right-sided headache pain can be a feature of various headache disorders, including cluster headaches, migraines, and secondary headaches due to structural abnormalities. While the side of pain may aid in diagnosis, it does not necessarily correlate with the severity or healthcare use. Thorough clinical evaluation is essential to identify the underlying cause and provide appropriate treatment.
