Main Symptoms of Sympathetic Cervical Spondylosis

When neck joints irritate the sympathetic nerves, the body reacts with a mix of head, eye, and heart-like complaints that can feel scary yet look normal on scans. Dull neck ache is the starting point. It spreads upward, wrapping the back of the head like a tight band. Vision then blurs. One moment the screen is sharp, the next it smears. Bright lights feel glaring, and pupils may seem uneven. Ears ring or fill with pressure, as if landing in an airplane. Some hear their own pulse whooshing at night. Dizziness flashes on with quick turns. The room does not... Learn more

Main Symptoms of Trigeminal Nerve Tumor

A trigeminal nerve tumor grows along the largest nerve that feeds the face. Because the nerve has three branches, symptoms show up in different zones of the cheek, jaw, or forehead. The first red flag is face pain that feels like electric shocks. It may last seconds or minutes and is often triggered by brushing teeth, a cool breeze, or smiling. Numbness or tingling follows. Parts of the cheek, lips, or tongue can feel “asleep,” making it hard to notice hot drinks or accidental bites. Chewing weakens. The jaw tires halfway through a meal, and you may hear clicks as...

Main Symptoms of Brain Cancer

Brain cancer can start in the brain or travel there from elsewhere. Signs depend on where the tumor sits and how fast it grows. Headache is the symptom people mention most. It often starts dull, wakes you at night, and feels worse when you bend over or cough. Nausea and vomiting may show up with the headache, especially in the morning. The sick feeling can fade after you throw up, then return later. Vision changes. You might see double, lose the outer edges of sight, or notice flashing lights even when your eyes are closed. Weakness or numbness creeps in.... Learn more

Main Symptoms of Head Injury

A knock to the head can shake the brain even when the skin looks fine. Watch for clues that start right away or build over the next day. Headache is the common first signal. It may throb, feel tight, or grow worse when you move your eyes or stand up. Thinking feels slow. You forget why you walked into a room, lose track of conversations, or give the same answer twice. Stomach trouble shows up next. You may feel queasy, throw up once, or keep vomiting long after the hit. Balance drifts. Walking turns clumsy, like weaving after spinning in... Learn more

Main Symptoms of Stroke

A stroke is a brain attack that strikes suddenly. The easiest way to spot it is to think FAST. F—Face: Ask the person to smile. One side may droop or feel numb. A—Arm: Have them raise both arms. One arm drifts down or feels weak. S—Speech: Listen for slurred words, mixed-up sentences, or trouble naming simple objects. T—Time: If any of these signs show up, call emergency services right away; every minute counts. Beyond FAST, other clues appear. Vision can blur or go black in one or both eyes. Walking turns wobbly, as if the floor is moving. A sudden,... Learn more
