Hello, I wanna ask about my headache that occurs mostly when I spend time under the Sun (e.g. Playing cricket in hot season) or when I go outside in afternoon. Means when I face Sun in hot season for more than 30 min. I have to face this irritable headache. And without taking saridon or any tablet, it doesn't disappear. Please please help me out from this. Please tell me in detail. For 5 to 6 yrs. Whenever I face Sun in hot .then i've to tolerate this headache mostly.(mostly, when I play cricket or do something physical work). It occurs in whole head (not one or both side.in mid side. After taking saridon, it disappear. If I dnt take then after sleeping, it can be low but when I shake my head, it occurs.
