Hello
I understand your concern.
The pain in head you are getting now is not due to the trauma you had in your childhood.
It may be because of hypertension/migraine/
tension headache.
Information you provided is too less to arrive at any diagnosis.
I need to ask you,
-what is type and site of headache?
-do you get palpitations?
-do you get an aura of nausea,vision disturbances before headache ?
-do you experience arm or leg weakness ?
If I were your treating doctor,I recommend,
-Blood Pressure measurement,blood glucose,
blood lipids,ophthalmic examination for visual acquity and
intraocular pressure measurement by tonometry.
-Take analgesics like
acetaminophen or ibuprofen twice for couple of days along with antacids.
-Visit to
neurologist for further evaluation if headache persists.
Hope this information helps.
Feel free to ask any more doubts.
