Right-Sided Headache: Understanding Causes, Significance, and Quick Relief Strategies
Headaches on just one side, typically the right, can be a common occurrence for many people. Here's what you need to know about the causes and remedies for those pesky one-sided headaches.
A headache on the right side can be caused by a variety of conditions, some of which only affect one side while others can potentially be more localized.
Right-sided headache triggers
Single-sided conditions
Some possible causes of a right-sided headache include:
- Temporal arteritis: This inflammation of the temporal artery may be found on one side and can create symptoms like fatigue, jaw pain, and tender temples.
- Trigeminal neuralgia: Characterized by intense facial and head pain, usually affecting one side at a time, this condition occurs due to interference with the trigeminal nerve at the base of the brain.
- Sinus headaches: Individuals with a deviated septum are more prone to sinus headaches, which are often confined to one side.
Bilateral conditions
Occipital neuralgia generally affects both sides but can lead to one-sided symptoms. This condition happens when the occipital nerves, which run from the top of the spinal cord to the scalp, get damaged or inflamed. Typical signs include sharp pain at the back of the head and sensitivity to light.
Other possible causes of headaches affecting the entire head or just one side include:
- allergies
- aneurysm
- fatigue
- head injury
- infections, like sinus infections
- fluctuations in blood sugar levels due to missed meals
- dehydration
- muscle strains or knots in the neck
- tumors
Medication use
Headaches can also be a side effect of various medications, including prescription or over-the-counter ones, and can result from overusing OTC painkillers like acetaminophen (Tylenol), aspirin, or ibuprofen (Motrin, Advil). This type of headache is known as a medication overuse headache and is a common issue affecting a significant portion of the global population.
Types of headaches affecting the right side
There are numerous types of headaches, some of which are primary, where headache is the primary symptom, and secondary, where headache occurs as a symptom of another condition. However, migraines and cluster headaches are the most probable causes of a headache on one side of the head. Tension headaches may also cause pain on one side in certain people.
Migraines
Genetics play a role in migraines. Migraine headaches are characterized by throbbing pain in the head. Gratefully, having a headache on the same side every time is not always a sign of a more serious complication, such as a tumor. Common symptoms associated with migraines include vision changes, nausea, sensitivity to light and sound, and vomiting.
Cluster headaches
Cluster headaches are severe headaches that occur in cyclical patterns and cause intense pain around one eye. They may also radiate to other areas of the head and face, as well as the neck and shoulders. People usually experience frequent headache attacks for weeks or months before a period of remission. Other symptoms include facial sweating, pale or flushed skin, red or watery eyes, restlessness, stuffy or runny nose, swelling around the affected eye, and agitation.
Tension headaches
Tension headaches are the most common type of headache, affecting around 1 in 5 people. While they typically affect both sides of the head, some people may experience symptoms on just one side. Regular tension headaches can cause chronic headaches lasting more than 15 days each month. Symptoms include dull, aching pain, scalp tenderness, tender or tight shoulder and neck muscles, and tightness or pressure across the forehead, sides, or back of the head.
When to consult a doctor
While many headaches will resolve without treatment, people who experience headaches frequently should consider consulting a doctor to identify the underlying cause. If headaches are accompanied by the following symptoms, seek immediate medical attention:
- vision changes
- confusion
- fever
- head injury
- increased pain during movement
- neck stiffness
- numbness
- personality or cognitive changes
- rash
- sleep disturbances
- slurred speech
- weakness
If a headache only occurs on one side every time, this is cause for concern and should prompt a medical evaluation.
Frequently asked questions
Understanding the location of a headache helps a doctor diagnose the type of headache affecting a person and plan appropriate treatment. For example, headache pain at the front or on one side may indicate migraines or cluster headaches. Some headaches may resolve on their own, but if symptoms are severe, persistent, progressively worsening, or accompanied by other symptoms like vision changes or slurred speech, seek medical advice.
Dehydration can cause or worsen headache symptoms and headache disorders. Prevent dehydration headaches by staying adequately hydrated. To treat this type of headache, doctors typically address the individual's dehydration by replenishing their fluids.
Contrary to popular belief, a one-sided headache does not always mean a migraine. Other possible causes include neurological issues, tension headaches, medication side effects, and allergies.
