16 Causes of Left Migraine

Having a headache is very painful, especially if you have a migraine headache. When migraine headaches strike, your daily activities will certainly be disrupted. Yes, migraine headaches are indeed considered very painful and disturbing activities.

A migraine is a moderate to severe headache that feels throbbing which is generally only about one side of the head. This disease is more common in women than men. According to WHO research results, of the total human population aged 18-65 years who reported experiencing headaches, about 30 percent were migraine headaches.

In some people, migraine attacks can appear only a few times a year. However, in other patients, migraines can appear up to several times a week. In certain cases, pain can appear on both sides of the head and even attack the patient’s neck.

In order for your head pain to be dealt with appropriately, then you must know the underlying cause and how to deal properly with it.


1. Hunger

The first cause of left migraine is hunger. The brain needs sugar (glucose) from food as fuel to function optimally. If you don’t eat, your blood sugar levels will decrease (hypoglycemia), as a result the brain responds to a headache.

2. Stress

The next cause of left migraine is experiencing stress. When we experience stress, the body releases chemicals that have ‘figh or fligh’ properties. These chemicals make the muscles tense and change the blood flow, both of which cause headaches.

3. False eating

Other causes of migraines that are rarely realized are eating wrong. Certain foods are found to cause headaches, especially those containing preservatives. Foods that trigger headaches include old cheese, red wine (drinks), nuts, and processed meats.

4. Alcohol

Other causes of left migraine are due to alcohol consumption. Beer, wine and other alcoholic beverages contain ethanol, a chemical that triggers headaches because it can widen blood vessels. When the blood vessels around the head widen, it will cause pressure and sensitivity to the nerves in the head.

5. Lack of sleep

The next cause of migraine is lack of sleep. Disorders of lack of sleep or insomnia can lead to left-sided headaches. Once the headache occurs, the pain can also make sleep less sound at night, so what happens is a vicious circle pattern. People with other sleep disorders such as obstructive sleep apnea are also more prone to headaches.

6. Incorrect sleep position

The cause of left migraine which is rarely realized next is the sleeping position. The most common problem is when the head position is not right, or the pillow is not supported. In the morning when you wake up, you will feel that your neck feels painful or stiff, even to look right or left looking down. If the neck muscle tension is on the left side, then this could be the cause of the left headache.

7. Infection and allergies

Other causes of migraine are due to infection and allergies. Left or right headaches are often caused by respiratory infections such as the common cold or cold. No wonder, because a fever and blocked sinus tract can cause headaches which are symptoms of sinusitis. Likewise with allergies that affect the sinuses, causing pain and pressure behind the forehead and cheekbones.

Moreover, in cases of serious infections such as encephalitis and meningitis, this condition can cause more severe headaches. Other symptoms include seizures, high fever, and stiff neck.

8. Problems with teeth and gums

Other causes of migraine are dental and gum problems. When teeth or gums experience inflammation and pain, the pain can spread to the head. Depending on which side is affected, if the one that is sick is the left tooth and gums, then that could be the cause of the left headache.

9. Excessive medication

The cause of migraines that may be rarely realized is excessive medication. Medications for treating headaches can actually cause more headaches if used more than two or three days a week. This headache is known as medication overuse headaches, or rebound headaches. Headaches occur almost every day, and pain starts when you wake up in the morning.

Medications that can cause excessive headaches include: aspirin, acetaminophen (paracetamol), ibuprofen, naproxen, triptan, ergotamine, oxycodone, tramadol, and hydrocodone.

10. Nervous disorders

The next cause of left migraine is a nervous breakdown. The presence of nerve problems can sometimes be a source of headaches. Occipital neuralgia: The occipital nerve is located at the base of the skull. This irritation of the nerves can cause severe pain, pricking in the back of the head or base of the skull. The pain can last a few seconds to minutes.

Giant cell arteritis: Also called temporal arteritis, this condition is caused by swelling of blood vessels – including temporal arteries along the side of the head. Symptoms can include headaches and pain in the jaw, shoulders and hips, along with visual changes. Trigeminal Neuralgia: The trigeminal nerve functions as a recipient of sensory stimuli on the face and part of the head. If this nerve is disturbed, then the pain feels so great on the side of the affected face to the head.

11. Hold your head tight

Another cause of unconscious migraines is tight headgear. Wearing a helmet, hat, or other headgear that is too tight can put pressure on one or both sides of the head. Over time it can cause pain.

12. Concussion

The other cause of migraine is due to having a concussion. A hard blow to the head can cause traumatic brain injury. The pain that arises according to the area hit, can be left or right. If a concussion occurs, it is not only a headache, it is accompanied by confusion, nausea and vomiting.
Can also be a sign that you are suffering from an illness

13. Glaucoma

The next cause of migraine is glaucoma. Glaucoma or increased pressure in the eyeball is very dangerous because it can cause blindness. If you feel pain in the eyes, blurred vision, and angry headaches, then you should immediately seek treatment before it’s too late.

14. High blood pressure

The other cause of left migraine is due to high blood pressure. Usually, high blood pressure does not cause symptoms. But in some people headaches can be a sign of hypertension. This can be known through blood pressure checks.

15. Stroke

The next cause of left migraine is stroke. Blood clots can block blood vessels to the brain, cut off blood flow and cause strokes. Bleeding in the brain can also cause strokes. Sudden and severe headaches are a warning sign of a stroke.

16. Brain tumors

Another cause of migraine is a brain tumor. For those who often experience intense headaches accompanied by other symptoms such as loss of vision, speech problems, confusion, difficulty walking, and seizures, it must be aware of the tumor in his brain. This can only be known through examination, both physical and also supporting, such as CT Scan and MRI.
