Head ache if it is sudden and splitting is a cause for concern and is generally caused by an elevated blood pressure. Constant head ache can be categorized as migraine and this needs symptomatic treatment. Drink plenty of water, eat every two hours, rest, do not go out in the sun, avoid any fragrances that bother you, also avoid any foods that trigger the same. At times even chocolate can trigger a head ache. Right now yes mention it to your doctor over the phone, take paracetamol after discussing with the doctor, get a hot oil massage for your head and dim the lights and sleep.

try to mention this to ur doctor in your next visit. if it's bad go see the doctor. I had the same problem. my doctor asked me keep a note of my BP everyday. my BP was normal. so I was prescribed pcm 650 sos basis. I usually did home remedies cause I used to have a headache almost everyday. I used to get head massages. or soak a towel in ice water and put on my face and sleep. it helped me a lot.

few reasons are associated with this type of headache but one basic thing is you need to take atleast 3-4 ltrs of water a day and the headache reduces.

even I hd dis problem...it's coz of acids made in our stomach...never starve urself ...after short intervals keep eating smthing...als wn u wake up in morning first eat SM sweet ...

check your vitamin d levels, are you taking calcium supplements? Also some time it happens because of vitamin b12 levels also.
