I've had spots on my lungs for about 30 years, and they're not even
related to my cigarette smoking. I had been exposed to TB in a nursing home while visiting my ailing father-in-law. We found out about it when my wife (now - ex) had to get a 'patch' test to be licensed for home kiddie care. I had to get one, too -and it was positive, so a chest x-ray was ordered.
It was determined that the exposure in the nursing home
was the culprit.
More recently, my injured son was in shock-trauma for 6 weeks,
and ICU for 2 more. There.... I picked up MRSA & freaked, ....until my doc told me that many medical professionals wind up with it, as well. Occupational hazard.
But I was 'on the edge' for a few days about it.
(I'm still not so thrilled about it.) What if my PN progresses to autonomic? Then the MRSA will put me in a heap of big trouble.
