Detailed Explanation
One-sided headaches have specific causes that differ from general headaches:
Most Likely Causes
- Migraine (most common) - Throbbing, pulsating pain - Usually one side, can switch sides - Often with nausea, light/sound sensitivity - Lasts 4-72 hours - May have visual aura
- Cluster Headache - Extremely intense pain around one eye - Occurs in "clusters" for weeks/months - Eye watering, nasal congestion on affected side - More common in men
- Tension Headache - Can be one-sided - Pressing/tightening sensation - Often from muscle tension in neck/scalp

Why do I wake up with a headache every morning?
Morning headaches commonly result from sleep apnea, teeth grinding (bruxism), poor sleep position, dehydration, or caffeine withdrawal. High blood pressure and medication overuse can also cause them. Frequent morning headaches should be evaluated by a doctor.
Why does the room feel like it's spinning?
A spinning sensation (vertigo) is usually caused by inner ear problems like BPPV, vestibular neuritis, or Meniere's disease. It can also result from migraines or, rarely, stroke. Vertigo lasting more than a few days or with neurological symptoms needs medical attention.
Why do my hands go numb at night?
Nighttime hand numbness is most commonly caused by carpal tunnel syndrome, which compresses the median nerve when wrists bend during sleep. Other causes include sleeping position, cervical radiculopathy (neck nerve compression), or peripheral neuropathy. A wrist brace at night often helps.
