@TheJen @kimlockhartga There are spores out to get you in desert environments. Someone I knew from HS contracted Valley Fever. His father, an archeologist, also. The son survived his bout. His father passed away. It also became an issue in Los Angeles after the Northridge quake kicked up a lot of desert dust.
I hope you feel better soon.
In case this might be what's bothering you:
