My husband and I believe we are suffering the aftermaths of viral meningitis, but we're not sure. A malady struck us after an international flight from the US to Germany in August 2014. Woke up dazed, confused, with pressure in the back of my head. Husband had pressure, discomfort on sides of head and felt nausea. We endure two week vacation. Flight back was tolerable. That night we had the WORST, WEIRDEST headaches ever!! Aspirin didn't help. Got better for two days, then it hit the back of my head again, and agony for three more months. I'm a good deal better now, but still get pressure in my head often and sometimes confusion. Husband suffering similar, long lasting off and on symptoms. Doctors of no use! Anyone else experienced this???
