NY, jeez, you just scared me, with the CT scans of head and chest. You've had a lot of what I have (I don't have asthma sx quite as severe as you do, doesn't impact my riding). I am sure I have a sinus infection. I was sick about a month ago, thought I was better, (I was) and now it's back, even more. I've had years of sinus x rays, scans, etc and nothing is wrong. My ear hurts, too. It's the same every time. I just don't feel like going to the doctor or taking an antibiotic. My doctor is close, but I might just go by the minute clinic.
Heading for bed and it's 7:50!
