@merpreb It wasn't a scar. The doctor told me it was liquid. Probably infectious stuff. But the problem is if it didn't go away or got worse after all this time wouldn't that mean I have an antibiotic-immune lung infection? What could they do except lung surgery? Does anyone in the group know anyone who has a lung infection that won't resolve? Of course, with a new scan it opens new possibilities-they may find a tumor in addition to unresolved infections, in which case I won't have to concern myself with the infection.The infection would be trivial by comparison. If I didn't have that follow-up x-ray I wouldn't be dealing with any of this. Too bad you deleted the African salesman with the herbal cure for emphysema.I might need the herbal doctors name after hearing the results of this x-ray.
