Hi Beth, This may be somewhat unrelated, but my brother just had a hernia repared. the xrays they did postop showed that he had a 'nodule' on his lung. he was all freaked about it until the dr came in to tell him this was nothing to worry about.
Even tho they show it to be lymph nodes, I hope it turns out to be a 'no worry' and the meds knock it out.
love ya!
