Basically I think it slowly invades your lungs but finally your immune system figures it out and goes all-in. What triggered it was some vigorous excersize which wiped me out. I call that day 1 but it was after over a week of the cough. Day 1-2 occasionnaly had a 99.0F fever but often lower/normal. Had two nights where I felt congestion developing in lungs and then third day got to 100.8F at 5pm... that night-BAM-woke up at 4am with cold sweats and a strong even burning in both lungs (probably immune system working on it). Lungs felt raw breathing in air. Turned on the shower to get some humidity and the burning subsided but then lungs started swelling up and breathing difficulties began. Luckily I took a bunch of benedryl and was able to breathe more after an hour of calm, but was close to calling ambulance. After that I've now had one OK night with a lot of localizing immune activity but at a lower level. On a scale from feeling lousy (1) to dead (10) the progression each night was 1,2,5,2.. (and hopefully continuing down..).

Get well soon, and thank you for sharing!
