Head pain on the left side can be concerning. It can result from various causes, some benign and others more serious.
Common causes include tension headaches, sinus infections, migraines, and cluster headaches.
Migraines often involve severe pain, sensitivity to light and sound, and other symptoms.
Cluster headaches are intense, short-lived, and often strike at the same time daily during a cluster cycle.
Sinus infections can cause pressure and pain, affecting both sides or just one.
Occipital neuralgia leads to sharp, aching pain in the upper neck and head.
Hemicrania continua is a rare, chronic one-sided headache with intense episodes.
Giant cell arteritis involves inflammation of arteries, often at the temples, and can lead to vision problems.
Trigeminal neuralgia causes sudden, severe facial pain and can be triggered by various factors.
Bell's palsy results in facial weakness or paralysis on one side and may be linked to viral infections.
A stroke or brain aneurysm can also cause severe, sudden head pain and requires immediate medical attention.
If you experience persistent or severe one-sided head pain, consult a healthcare professional for proper diagnosis and treatment.
