Hello, It is due to visual disturbances that you are having headache. You have history of migraine and retinal migraines also cause visual problems (blurring of vision due to eye strain, need to wear glasses for correction of myopia, hypermetropia, astigmatism, open angle glaucoma, cataracts), these are associated with headache. Ibuprofen helps relieve headache. Visit ER, see an eye specialist and get an eye check up done. You may need glasses or medications. Hope I have answered your query. Let me know if I can assist you further.
