In 1996, I had these same symptoms. They did an xray where they found a small mass resting agains one of my bronchial trees. Upon removal of it, the symptoms alleviated.
I'm allergic to PCN, and Cephalsporins.
I recently moved back to Austin, TX, after spending 2 years in Amarillo, Texas. The building I was working in up there was being renovated and they had an abatement going to to remove the asbestos. My coughing initially started up there within the last year.
I have no fever.
I'm tired of coughin so much or so violently that I'm urinating when doing it, to the point where I've had to invest in extra pads.
