Hello! I have been through your question. According your concern you should know that many viral infections can either directly or indirectly cause headache. The headache related to these viral infections appears to be related to the fever, the body’s production of interferon, and other elements of the immune system combating the viral infection. Headache may also be associated with those viral infections that affect the upper respiratory tract, such as the common cold virus, the Rhinovirus. What I am afraid usually in this situation is that some times a severe headache may also result from viral infections that specifically attack the brain and its coverings known as encephalitis and meningitis. So, except the ibuprofen and paracetamol I suggest to meet again your doctor to do a physical examination in order to exclude an encephalitis and meningitis and to take the right medication. I hope my answer help you. I wish you a quick recovery.
