Missed the Whole Month

I've gotten in several runs in April, but not one of them was 100%. I had 6 days in a row of running. The rest of the time I spent coughing, and coughing, and coughing some more. I coughed so hard I thought I was going to throw-up my guts. I coughed so hard so often my abs are sore. I coughed all the way through the month. They wouldn't let me work because everyone was tired of hearing me cough. I coughed so hard I had a headache. I had to intertwine my fingers and clamp my palms on my temples before each coughing fit because it felt like my head would explode during the effort. I was coughing convulsively.
The doctor said it was Reactive Airway Disease, of which my asthma is just part of it. My hypersensitivity to pollen, smoke, or anything else causes my respiratory system to attack me. He stuck me on a steroid that got rid of most of the convulsive coughing, but that was a week ago and it is starting to return.
This elevates the risk of pneumonia. I've had acute pneumonia, walking pneumonia, and someday I'll probably die of pneumonia.
They x-ray'd my lungs and sinuses and they were clear, so he said I wasn't sick from an infection - just being attacked by my respiratory system.
I'm taking Claritin to help control my allergies. This Spring has been hell.
What fun.
This may end my racing career. Virtually no training this entire month. Friends are bragging how they've logged 300 miles, and I haven't made it 90 for the entire month.
I have Collegiate Peaks 50M in 6 days, and I'm still coughing. I may have to bail.
