Thanks for writing in.
The possibilities I can think of are migraine
, high blood pessure, drug abuse
etc. You haven't mentioned your age , so it is difficult to say which one of the above is more likely.
Is the pressure on the head more on the back or the sides? ( If on the back of the head, and neck, more in favour of tension headache/ hypertension
What investigations were done while you were at the hospital?What was the probable What was the probable diagnosis?
Any history of aura, sensitivity to light or noise? Any family history of migraine. (if yes,more in favour of migraine)
Kindly get back to me with the above details.
Hope this helps.
