I have the same thing Kristen....I just noticed them....they remind me of "old age spots" that older people get later in
life. I am 62 but not old enough for these spots. There are like two or three at a time that are purplish/reddish in
color and then slowly disappear. But then others pop up...they are on either arm. I am unsure of what they are
also and haven't found a good explanation online so far.
