Main Symptoms of Skull Base Tumor

A skull base tumor sits deep beneath the brain, close to nerves and blood vessels that control everyday functions. Because space is tight, even a small bump can send out quiet but steady warnings. The first red flag is a one-sided headache that feels like pressure behind the ear or eye. It hangs around for weeks and does not care about painkillers. Hearing then fades on the same side. Voices sound underwater, you raise phone volume, yet the ear still feels plugged. Facial twinges come next: quick electric zaps across the cheek or jaw that feel like a dental problem... Learn more

Main Symptoms of Intracranial Hematoma

An intracranial hematoma is a pocket of clotted blood inside the skull. It can grow quickly after a head bump or appear days later when a small vein keeps leaking. As the clot expands it squeezes the brain and raises pressure, producing clear warning signals. The first sign is often a headache that ramps up over minutes to hours. It feels like a steady drum inside the head and is usually worse when lying flat. Nausea and vomiting can follow the headache without any stomach upset. The vomit may come on suddenly and bring brief relief, then return. Thinking becomes... Learn more

Main Symptoms of Intracranial Cholesteatoma

An intracranial cholesteatoma is a slow-growing pearl of shed skin cells trapped deep inside the skull. As it expands it irritates nerves and blocks fluid paths, giving off quiet but stubborn warnings. The first clue is a one-sided headache that feels like dull pressure behind the ear or eye. It marches deeper over months and does not care about aspirin. Hearing fades on the same side. Voices sound underwater, you crank the phone volume, yet the ear still feels plugged. Brief dizzy spells pop up. The room tilts for a few seconds when you roll over in bed or look... Learn more

Main Symptoms of Intracranial Infection

An intracranial infection means germs have reached the brain or its coverings. The immune system sounds an urgent alarm, and symptoms climb quickly. Fever is usually first. Temperature spikes to 38–40 °C (100–104 °F) and can swing from chills to sweats within an hour. Headache follows fast. It feels like steady pressure or a band tightening around the skull and grows worse when you move your head or bend forward. Neck stiffness appears early. Tilting the chin toward the chest feels like a pulled muscle, and bright light may make the pain spike. Nausea and vomiting hit without stomach upset.... Learn more

Main Symptoms of Increased Intracranial Pressure

Increased intracranial pressure means the fluid and tissue inside the skull are under too much tension. When the brain is squeezed, warning signs show up fast and tend to pile on top of each other. The headline symptom is a steady, pounding headache that feels like your head is over-filled. It is usually worse when you lie flat, cough, or bend forward and may wake you from sleep. Vision blurs next. Lights seem too bright, you see double for a few seconds, or the edges of your sight turn gray. Closing one eye does not clear the blur. Nausea arrives... Learn more
