Today, i woke up with an intense headache and extreme nausea i almost vomit. it was like a sudden wave of nausea and i felt terribly bad. is it normal?

See md: See your medical doctor and rule out any precipitating factors that are medical in nature. If nothing comes up then call a dentist to evaluate your jaw joint which can cause many muscle tension issues such as headaches.

No: Not normal. Unless you already know the cause, see your doctor for evaluation and treatment. Possible causes include migraine headache, pregnancy, dehydration, aneurysm, drug withdrawal, electrolyte, imbalance, flu or cold, and others. Your condition needs to be evaluated in person.
