Have anyone of you been flying or heard/seen anyone fly on a plane with HSV2 in mouth? I just worried if the pressure will open more route at the back of the sinus for the HSV2 viruses to travel/hide/attack. My doctor does not know about this, and I can only gamble with less than 4 hours while swallow valtrex at the same time. I appreciate any response, for I might need to fly to see a doctor.
