About 50% of the population suffers from some form of headache disorder. Some people experience headaches as a minor inconvenience. For others, these headaches can be debilitating.
A headache can sometimes feel like your entire head is throbbing. Sometimes, a headache can feel like a sharp pain at a particular area or point.
Although a headache on the left side of your body is often classified as a “migraine”, there are other possible causes.
Migraine
Migraines are a headache type that can be accompanied by other symptoms such as nausea and light sensitivity. Migraines usually cause a throbbing, intense pain on one side.
A migraine may be accompanied by an aura, a sensory or visual disturbance such as flashes or blind spots.
Migraines cause the majority of headaches on the left side. Around 1 in 6 Americans suffer from migraines.
Cluster Headaches
Cluster headaches cluster headaches tend to occur as a group.
They are characterized by headaches that occur repeatedly over a period of days or weeks and then disappear for a few weeks or months.
Cluster headaches, although rare, can be extremely painful.
Cluster headaches can be accompanied by other symptoms such as watery or red eyes, a runny or irritated nose, or flushing and sweating, especially on the side of the face where the pain is experienced.
Sinus Headaches
Sinus headaches can be felt on either side of the head. Other sinus symptoms such as a runny or stuffed nose, facial pain, or congestion are also present.
Inflammation of the sinuses is the cause of sinus headaches. It can be caused by an infection, allergies or other factors.
