Barbara,
Hmmmm… I’m so sorry you’re experiencing such a puzzling symptom… I, myself, have strange skin issues that are chronic, but nothing quite like that.
Do these happen on only one part of the body or are they placed randomly?
I will keep my eyes and ears open, so if I learn of any possibility, I will chime in…
(I love researching random things :-))
Take care,
~Kelly~
