Various issues in the brain can cause one-sided pain in someone’s head.
The following neurological conditions may be responsible for headaches on one side:
- Occipital neuralgia: This occurs when occipital nerves, which run from the top of the spinal cord to the scalp, become damaged or inflamed. Symptoms include sharp pain in the back of the head and neck and sensitivity to light.
- Temporal arteritis: Arteries in the head and neck become inflamed with temporal arteritis. Along with muscle pain, it causes a severe headache on the side of the head. Other symptoms include fatigue, jaw pain, and tender temples.
- Trigeminal neuralgia: This causes intense pain in the face and head. The pain usually affects only one side at a time. It occurs due to a disruption to the trigeminal nerve at the base of the brain.
Headaches can be a side effect of prescription or over-the-counter (OTC) medications. They can also occur due to someone overusing medication, including OTC painkillers such as:

Early treatment is key to reducing the length and severity of symptoms. Treatments include OTC or prescription medication, such as nonsteroidal anti-inflammatory drugs (NSAIDs). Prevention involves avoiding triggers and using preventive medications in some cases.
People typically experience frequent headache attacks for weeks or months before a period of remission.
Other symptoms of cluster headaches include:
- facial sweating
- pale or flushed skin
- red or watery eyes
- stuffy or runny nose
- swelling around the affected eye
Males tend to experience cluster headaches more often than females. The exact cause is unknown, but smoking, alcohol use, and a family history of cluster headaches may increase risk.

- tender or tight shoulder and neck muscles

People can treat occasional tension headaches with OTC pain relievers or home remedies. People with frequent tension headaches may need to change their lifestyle, identify and avoid triggers, or use prescription medications.
Many headaches will resolve on their own without any intervention. People who experience headaches regularly should make an appointment with their doctor to identify the underlying cause.
Anyone who experiences the following symptoms alongside a headache must seek medical attention urgently:
- changes in vision

- moving away from bright or flashing lights, loud noises, and strong smells
- stopping slouching, as muscular tension can cause headaches
- taking a warm bath or shower
- taking a break from screens, including computers, tablets, and television
- taking OTC painkillers, but avoiding excessive use as this can trigger rebound headaches
- doing breathing exercises to reduce pain and alleviate stress and anxiety
- using aromatherapy, diffusing oils such as eucalyptus, lavender, or peppermint oils for tension headaches
Below are some common questions about a headache on one side of the head.
Does headache location mean anything?
Understanding and identifying headache location may make it easier for a doctor to diagnose the type of headache affecting someone and plan appropriate treatment.
For example, headache pain at the front or on one side of the head may indicate migraine or cluster headaches.
How do you fix a right sided headache?
Some headaches may go away on their own. People can use at-home treatments, such as OTC pain relief medications or having a nap, to relieve symptoms.
However, if headaches are severe, frequent, progressively painful, or occur alongside other symptoms, including vision changes or slurred speech, people should speak with a doctor.
What is a dehydration headache?
To treat this type of headache, doctors typically treat the person’s dehydration, usually by replenishing their fluids.
What do migraines on the right side mean?
Migraines often affect one side of the head. Possible causes include nerve issues and inflammation.
Is a one sided headache always a migraine?
No, a one sided headache is not always migraine. Other causes include neurological issues, medication side effects, and allergies.
Headaches are a widespread health complaint, affecting most people at least occasionally.
Most headaches are not cause for concern. Usually, symptoms will resolve within minutes to hours. Alternatively, people can ease symptoms with OTC medications, lifestyle changes, and home remedies.
People should see a doctor if headaches are severe, persist, or get progressively worse. Even if a migraine or a cluster headache is responsible for the pain, a doctor can prescribe treatments to manage symptoms and reduce the frequency of the headaches.
