What causes headache due to brain tumor?
The type and intensity of pain depends on the location and growth of the tumor. When the brain tumor compresses the vital functioning organs in the skull like the veins, nerve fibers, large arteries and the skull wall, a pattern of headaches is triggered.
When a tumor grows in the brain, there could be brain swelling. This causes intracranial pressure (ICP). ICP is the pressure exerted on the brain tissues and cerebrospinal fluid that surrounds the brain.
In the case of brain tumor, the headache comes along with a sequence of other symptoms like vomiting. Seizures or body convulsions is another symptom of brain tumor post which the person experiences a dull headache and weakness.

There are striking similarities between the headaches in the case of migraine and those in brain tumor. Migraines can also cause nausea for some people. But the migraine pains do not occur with seizures or loss of control. Patients should also note other changes in the body like numbness in limbs, dizziness, vomiting, loss of sensory control, etc. The ultimate solution here to seek a neurologist and get checked. The specialist will be able to clearly distinguish and figure out the nature and cause of headache. Migraines are common and need not be worried about.
