A Flaky Question

Hi all
I suffered fairly bad burn damage after rads - so much so that my BC nurse laughed when she saw how red it was and called in a colleague to take a peep, h’m. Well that was over a year ago and the colour has lessened considerably tho it is still darker than the other one. Last night when I was undressing I noticed quite a few flakes of dead skin in my bra and the same this morning in my sleeping bra - yuck! Anyone come across this before?
Love to all, Laine
