Migraine

A migraine is a headache that causes severe throbbing pain on one side of the head. Lifestyle changes such as staying hydrated, managing stress, and keeping a regular sleep schedule can help prevent them.

Sciatica

Sciatica is when you get pain, tingling, or numbness that starts in your lower back and travels down your leg. It is caused by irritation or pressure on the sciatic nerve.

Dizziness

Dizziness is a lightheaded or woozy feeling that can make you feel off balance or like the room is spinning. It can happen due to dehydration, low blood sugar, inner ear problems, or even just standing up too quickly.

Carpal tunnel syndrome

Carpal tunnel syndrome is a condition where a nerve in your wrist (the median nerve) gets squeezed or compressed. It causes tingling, numbness, or pain in your hand and fingers.

Head injury

Head injuries can range from a mild bump or concussion to something more serious like a skull fracture. You should see a doctor if you have symptoms like confusion, vomiting, a bad headache, or faint.

Headache

A headache could be a sign of something serious if it comes on suddenly and feels very intense, is different from your usual headaches, or is joined by other symptoms like confusion, vision changes, weakness, fever, or a stiff neck.
