Hello there we understand your pain and your concern towards your health. But there are many reasons for headache and they should.be sorted out. Yea as the other doctor has already told you that vomiting post headache denotes increased pressure in the head. But we can avoid this to some extant by avoiding too much of stress. Having food in time, physical workout in the morning and fresh air etc. You need to consult a Neuro physician as other doctor suggested. Thank you

Headache that ends with vomiting usually denotes increased pressure inside your skull I would suggest you to kindly consult a Neurosurgeon at the earliest
