Headaches are among the most frequent health issues across the globe. In the last year, between 50 % to 75% of adults have suffered from headaches. Of these people, at least 30% have suffered from migraine.

Headaches can affect multiple regions of the head, and, in some cases, may be on only one side. This article will look at the kinds of headaches that trigger this type of pain on one side and causes, treatment options and the right time to consult an expert in healthcare.

Left Side vs. Right Side Headaches

Sometimes, headaches only show in one area of your head. It could be on the left or on the left side. It’s not understood why pain may be only present on the one part of the skull however, it is believed to be related to vasculitis. It’s an inflammation of blood vessels.

This head-related pain can result from a variety of headaches, such as headaches that cause migraines, cluster headaches and cervicogenic headaches.


The term migraine refers to a type of headache that is usually accompanied by the pain to throb in one head side. It can occur on the right or left side.

There are various types of migraine. This includes:

  • Migraine and aura is when a patient experiences certain warning signs before the beginning of a migraine, such as having flashing lights.
  • Migraine without aura It is the most commonly experienced migraine. It typically occurs without warning signal.
  • Migraine aura that doesn’t cause headaches It is also known as a quiet migraine. It occurs when aura or other signs of migraine are present however the patient doesn’t suffer from headache.

The pain of a migraine could vary from mild to severe. Over 12% the adults living in the United States are affected by migraine. They are 3 times more prevalent among women than males and are often a part of families.

Many people who believe they suffer from a sinus headache may actually be suffering from migraine.

Cluster headaches are uncommon, but severe pain headaches are known by how they develop. People who suffer from cluster headaches might experience an occasional headache for 4 up to twelve weeks. The headaches can occur in the form of a “cluster” and usually occur simultaneously throughout the day.

The pain of headaches that cluster can be intense and often occurs on the opposite face, or behind the eye.

The headaches that cause clusters of pain are most frequent among men, and typically begin when someone is in their 30s or 40s.

Once the pattern of headaches ceases then the headaches should go completely. Then the period of remission starts. It’s a time that is free of any symptoms of headache, and could last for months or even years prior to headaches recur.
