There are more than 300 types of headache, of which approximately 90 percent have no known cause. However, a migraine or cluster headache are the most likely causes of a headache on the right side of the head. Tension headaches can also cause pain on one side in some people. Sinus infections and allergies can cause headaches.
Headaches that result from sinus infections result from inflammation, which causes pressure and pain behind the cheekbones and forehead. A pain that is throbbing and lasts for a while, or that is accompanied by nausea or changes in vision or other senses, probably means a migraine. Light and noise make it worse. A migraine can hurt only on one side, but not all.
It's not very common, but a migraine can make your nose drip or clogged and your eyes watery, so you mistake it for a sinus infection. When you have migraines, they're usually triggered by the same things every time. Recognizing the pattern is key to avoiding them. Usually, a migraine will cause a shooting pain in the left or right side of the head.
However, migraine pain can sometimes affect both sides of the head, the back and front of the head and neck, and the face. A headache located on the right side of the head can provide a clue as to the type of headache you are experiencing. While most one-sided headaches are migraines, some may be due to an underlying problem in the nerves, blood vessels, or other structures within the neck, face, or brain. Migraines are usually one-sided, although many people may experience them on both sides and may get worse with movement and activity.
Migraines and tension headaches are considered the main form of headaches. These headaches are the main problem and are not caused by other problems, such as dehydration. Having a headache that lasts longer than 2 days or having more than 15 headaches in a month are also reasons to talk to a doctor. The problem gets its name because headaches tend to occur in groups, with one to eight headaches per day for a period of one to three months each year or two, often at the same time of year.
Tension headaches, which occur in about three out of four adults, are the most common of all headaches. If you have frequent headaches and use medicines, over-the-counter or prescription, or both, for more than 10 to 15 days a month, you may have medication overuse headaches. There are many types of headaches, but only certain types will be felt on the right side of the head. There are different types of headaches that can affect you only on the right side of the head, each of which has different and overlapping causes and symptoms.
However, you should see your health care provider if your headache pattern is changing or your headaches start to interfere with your daily routine. Along with a daily headache, people experience exacerbations of severe headache (a headache in addition to a headache). Cluster headaches are rarer than migraines and tension headaches, but they tend to occur in a certain location. Primary headaches exist on their own, while secondary headaches arise from pregnancy, medication, trauma, or an underlying disease, including infection or arthritis of the neck bones.
If the headache comes with cold-like symptoms and pressure or tenderness in the face, you could have a headache in your sinuses. Because the way you experience headaches can vary (and so do their underlying causes), you need to make sure you pay close attention to how headaches affect you. Headaches are common; it is estimated that nearly 75% of people worldwide have at least one headache each year. However, remember that overuse can lead to rebound headaches and a vicious cycle of drugs and headaches.
