Know what you mean about the bloody sneezing, I used to never have nose bleed problems, then 4 days after moving to Los Angeles from St. Louis, went to sneeze and oh boy! Co workers told me "welcome to LA"
Lived in Mohave dessert for about a year, had to use saline nasal spray and biotene quite regularly.
I think this is mostly from recent head cold, was up northern China in a city called Fuzhou, temps down in the 40,s no heat in the apartment, and got a good chill in the sinuses. Started sneezing, took about 4 days to take hold, then a good head cold. Felt like crud, chills, hot spells, green goo coming out of all sorts of orifices, etc. Even settled into my jaw causing a toothache. That was late last week, then had to drive 11 hours to Dongguan. Luckily they have a local brand cold medicine here that works wonders on the symptoms, doesn't dry you out too bad or make you drowsy. Great stuff.
Weather here very dry now so I suspect that only irritated things more. Then dumb me goes for a PET/CT....with a sinus infection. DUH! Sinuses still feel a little screwed up. I really think this is another false alarm, but we'll see what the other tests say.
Thanks for the support guys (and gals!)
