@robynmar, @colleenyoung Robyn and Colleen, I have not had the kind of skin problems that Robyn described. I'm not in the medical field, so I can't conclude with 100% certainty. But my personal opinion is that this is unrelated to the lung infections. I suggest do some googling with key words like lung infection, flaky skin, etc to see if anything come up. If I find anything, I will post it here. But I kind of doubt it. Come to think of it, long before I was diagnosed with MAC, there was a period of time I had all kind of severe skin problems, on my body and hands. My doctor says as we age our skin becomes thinner and more sensitive. So having skin problems at my age is common. She prescribed a couple of different kinds of ointment for my body and hand respectively. The problems cleared up in no time.
