Hello, if you're still there!
I'm fairly surprised to hear that. I also had a stubborn eye infection that relapsed few times back at 7 months before experiencing these headaches. I'm now more inclined to think that the virus may be connected to or triggering a mechanism in the hypothalamic region. Interestingly, I've been prescribed a drug that I've used for 11 months as an immune-modulator cyclosporine which is also extracted from fungi? maybe they all make sense who knows. FYI docs told me it's an epidemic adenovirus, nasty one.
