Common headaches are not pain brought on by the brain, because the brain does not have pain receptors. Sinus headaches are caused from pressure being exerted on the local nerves from inflamed sinuses. This pressure causes crushing pain during a sinus headache.
Likewise, migraine headache has a crushing pain from one side of the skull to the other.
A brain tumor is a tumor in the head that can damage the nerves in the brain or the central nervous system. It is one of the most deadly and major ailments. One of the main symptoms of the disease is brain tumor headaches.
In brain tumor headaches instead of benign internal arteries putting pressure on nerves, it is the brain tumor that does so. Headaches caused by a brain tumor occur in the early hours of the morning with a dull monotonous pain that disappears on its own. It is a non-migraine headache that can occur even during sleep. It can cause fatigue, throbbing at the location of the tumor, numbness and confusion. It is accompanied with seizures, double vision and neck pain. The headaches worsen if the patient changes his position, exercises or performs any kind of physical activity. Headaches can be sudden and they do not respond to general painkillers. Almost 18,000 people die every year in the US because of tumors in the brain.
There are other symptoms too. Nausea and vomiting are common. A brain tumor takes up space that is usually occupied by the brain and cerebrospinal fluid. It increases the pressure inside the brain cavity causing brain tumor headaches. This pressure triggers the vomiting centre leading to vomiting. It also disturbs the balancing mechanism inside the head causing nausea.
