I am having a headache over my left eye anyone know what could be the cause of it please help
I would think it was a sinus infection as well but when I have had sinus infections in the past there was usually noticeable congestion but this time there is not.
sounds like a sinus headache to me. Maybe you could try taking some Mucinex (or other decongestant) for a couple of days and see if that helps it.
