That’s what I have right now. I already drink a lot of water thinking I am dehydrated again but the headache is still here, so the only reason why I got this is food intolerance again. All I have eaten today is rice and the sour soup I have cooked and my culprit is half of the rice I have eaten, it is an old rice. I really have a weak stomach when I eat something old and stocked in the fridge for a long time. I know this headache will not disappear until I vomit all the food I have eaten but I don’t like doing it especially when I just ate chocolates., Haha
Anyway according to Mr. Wiki Food intolerance or non-allergic food hypersensitivity is a term used widely for varied physiological responses associated with a particular food, or compound found in a range of foods. It is negative reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but it is not a true food allergy. A true food allergy requires the presence of IgE antibodies against the food, and a food intolerance does not.
