Hi welcome to HCM... According to history you can have viral stomach flu associated with tension headache .... Viral infection can lead headache as constitutional symptom and that is increased by more working on computer... Here take pentoprazole to reduce acidity induced by viral infection... Avoid excess tea, coffe, spicy foods , smoking like gastric irritants... While working on computer after 1 hour working take some rest .... Take enough 6 to 8 hour sleep.... Try yoga and daily exercise for stress relief from job.... Basil leavea oil also help in reducing tension headache.... For headache simple analgesic can be taken.. Maintain healthy diet with more fruits.. Take care
