I get severe headaches on only one side of brain. Usually when i go out in sunlight, i immediately get headache. In the beginning, it used to vanish if i sleep for sometime. But now its not reducing even if i sleep. 3 years back i took Betacap plus 10 for 3 months. For few months i didn t get any ache but from past one year again i m getting severe headache. I am not able to control i take Grenil. sometimes its useful but sometimes it doesn t go... After childbirth the frequency of headache is more, my son is one year old.
