Migraine is a type of headache that can cause intense pain, nausea, and sensitivity to light and sound. Here are some common symptoms and prevention measures for migraine:

Symptoms:

1. Throbbing or pulsating pain on one or both sides of the head

2. Sensitivity to light and sound

3. Nausea and vomiting

4. Blurred vision or aura (flashing lights or zigzag lines in the visual field)

Prevention:

1. Identify triggers: Keep a migraine diary to identify triggers like certain foods, stress, changes in sleep pattern, and environmental factors like bright lights or strong smells. Try to avoid these triggers.

2. Sleep and exercise: Maintain a regular sleep schedule and get enough sleep. Exercise regularly but avoid overexertion.

3. Relaxation techniques: Practice relaxation techniques like deep breathing, meditation, and yoga to reduce stress and tension.

4. Hydration: Drink plenty of water and avoid dehydration, especially in hot weather.

5. Diet: Eat a healthy and balanced diet. Avoid skipping meals and limit caffeine intake.

6. Medications: Consult a doctor about preventive medications like beta-blockers, anticonvulsants, and antidepressants. Over-the-counter pain relievers like aspirin and ibuprofen can also be helpful for some people.

If you experience frequent or severe migraine headaches, it's important to seek medical advice to develop a treatment plan that's right for you.
