Your symptoms, severe headache with vomiting triggered by stress or anger and lasting 2-3 days, are most suggestive of a condition called Migraine, which is quite common and treatable. You should consider a medical evaluation, especially since the attacks are intense and prolonged, as a doctor can confirm the diagnosis and prescribe appropriate medicines to relieve pain, control nausea, and even prevent future episodes. In the meantime, try to identify and avoid triggers (such as stress, lack of sleep, or certain foods), maintain regular meals and hydration, and rest in a quiet, dark room during attacks. Seek urgent care if you notice warning signs like a sudden, worst-ever headache, vision problems, weakness, fever, or if the pattern is changing. Overall, while this is usually not dangerous, proper diagnosis and treatment can greatly improve your quality of life.
