About 3 weeks ago I went in to the ER due to some stomach troubles. While I was there they took a CT scan of my abdomen, which happened to catch a bit of my lower lung. Turns out the stomach issue was a virus but the radiologist found a spot on my lower left lung. I haven't seen the radiologist report but apparently it was described as "non-specific". I also do not know size. I took a follow-up x-ray at my doctor's office and nothing was found. We followed up with another full CT scan of the lungs one week after the first, and the radiologist found the spot again, same size, same description. The doctor is recommending waiting another three months and taking another scan before doing anything else. The doctor did mention that they saw some scarring on my lungs as well, but didn't mention anything about this spot being a scar. The doctor tells me not to worry, that most of these turn out OK, and that they don't think it is anything to be too concerned about. But, obviously, I am worried.
Backgound - 36yo male, non-smoker, but did work for a tobacco company for a few years where I was exposed to second-hand smoke on occasion. I do live in the Ohio Valley and am told that histoplasmosis is common in this area, although the doctor hasn't mentioned this as a cause for my spot. Am in good shape and run regularly. I did have some problem with a persistent cough late in 2005. Allergist had me perform some tests where I blew into a tube and they determined initially that my lung capacity was only 80% normal. After going on some meds that went up to 95% or so.
