Sometimes the muscles or blood vessels swell, tighten, or go through other changes that stimulate the surrounding nerves or put pressure on them. These nerves send a rush of pain messages to the brain, and this brings on a headache.
The hypothalamus and interconnected brainstem areas likely represent the neural sites responsible for the chronobiological features of some headaches, in particular the sleep-related attacks typical of the TACs, migraines and the hypnic headaches.
Migraine pain occurs when excited brain cells trigger the trigeminal nerve, one of five nerves located in the brain, to release chemicals that irritate and cause blood vessels on the surface of the brain to swell, according to the National Headache Foundation.
Going to sleep with an untreated migraine is commonly a mistake as it may worsen during the night and become difficult to treat in the morning. If a migraineur is sleep deprived, he or she can expect more migraines, while those who oversleep may wake with attacks that are very resistant to therapy.
Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. Some people may also carry genes that make them more likely to develop such headaches.
Headache is one of the most common symptoms after traumatic brain injury (often called “post-traumatic headache”). Over 30% of people with moderate to severe TBI report having headaches which continue long after injury. An even larger percentage people with mild TBI complain of headache.
Headaches have many causes, and most of them are not serious. However, in some cases, headache pain can be a symptom of a serious health condition or illness. If you're concerned about headache pain, talk to your doctor.
The good news is most headaches are not harmful or dangerous. But, about 10 percent of headaches are a sign of a serious health condition and require an emergency evaluation.
A number of sleep or health disorders, as well as personal habits, can trigger a headache when you wake up. Sleep apnea, migraine, and lack of sleep are common culprits. However, teeth grinding, alcohol use, and certain medications can also cause you to wake up with a headache.
If your pillow offers improper support you might wake up with a tension headache. A pillow that does not hold your head and neck in a neutral alignment with your spine can lead to neck pain and headaches. You'll want to consider your pillow's loft and firmness when determining if it is offering you proper support.
If left untreated, your headache pain will become moderate to severe. Pain can shift from one side of your head to the other, or it can affect the front of your head, the back of your head or feel like it's affecting your whole head.
No, it's NOT normal to get headaches everyday
Most people have headaches from time to time. But if you have a headache more days than not, you might have chronic daily headaches, which come in many forms – most of them pretty disabling.
In some cases, headaches can result from a blow to the head or, rarely, a sign of a more serious medical problem. Stress. Emotional stress and depression as well as alcohol use, skipping meals, changes in sleep patterns, and taking too much medication. Other causes include neck or back strain due to poor posture.
Without effective treatment, migraine attacks usually last for four to 24 hours. When you're suffering a migraine, even four hours is far too long — and that's why early treatment for a migraine is so important.
Seek emergency care if:
The headache is accompanied by high fever, confusion, stiff neck, prolonged vomiting, slurred speech or numbness or weakness, especially on one side of the body. Headache medication does not relieve chronic or excruciating pain.
A migraine is an extremely painful primary headache disorder. Migraines usually produce symptoms that are more intense and debilitating than headaches.
Pressure point LI-4 is also called Hegu (her-goo). It is found on the back of your hand. It is between the base of your thumb and index (pointer) finger (see Figure 1). Doing acupressure on this point can help with pain and headaches.
Although more studies are needed, a small study has shown promise for sleep being a combatant against headache pain. Out of 32 participants with persistent tension-type headaches, 81 percent said going to sleep was their most effective strategy for getting rid of a headache.
First, when you lie down, blood vessels that run through your head and your neck can become compressed, which temporarily restricts blood flow, causing headaches. Increased blood pressure on arteries from lying down can increase headache pain.
Clinical bottom line: Water intake is a cost effective, non-invasive and low-risk intervention to reduce or prevent headache pain. Rationale: Chronic mild dehydration may trigger headache. Increased water intake could help.
What Causes Brain Swelling? Injury, other health problems, infections, tumors, and even high altitudes -- any of these problems can cause brain swelling to occur.
