I have been suffering for 5 days now with severe headache. i have been taking penado and rotating with stillpain but it doesn't help. i dont have temp. 37.5 constant. when i bend my neck to back and down to chest it hurts in my neck and upper spine?

Headache: Severe headache of 5 days duration with upper back and neck pain on flexion warrants an investigation. Absence of fever is somewhat reassuring as viral meningitis would be considered as one possibility. I recommend consulting a neurologist so that appropriate testing will be done. If you're unable to be seen by a neurologist promptly, proceed to the hospital emergency room for evaluation.
