Dear Flow, if castor oil is available somewhere near you, apply a thin layer of it on your eyelids before you sleep at night. It keeps your eyes cool and relieves strain. If your headache is related to your eyes, then it'll definitely give you relief. Also, you'll have a good sleep( though I don't know if good and long sleep is something you can afford during exams😃). You can give it a try.
