The symptoms of severe headache
& vomiting can be attributed to an intra-cranial lesion.
Increased intra cranial pressure can cause vomiting.
Though symptomatic relief can be obtained with pain killers, unless the underlying cause is treated, symptoms will keep recurring.
Other causes of headache can be:
2. Cluster headache
3. Tension headache
4. Sinus headache
(due to sinusitis)
5. Underlying systemic cause like Hypertension
So, kindly consult your Physician & get a proper clinical examination done.
Investigations like estimation of blood pressure levels, complete blood count
, X ray of para nasal sinus & CT scan of brain will be helpful.
Wishing you a good health.
