I found this site in search of a diagnosis for these bumps
which I have too. Exact same symptoms. I'm searching now because I believe they're certainly caused by stress: it's the holiday season
and I'm definitely stressing out and, right on
schedule, they show up. They don
't bother me but my
family has come to recognize it like the bat signal that
I'm freaking out about something. I've come to use it as my
body's outward warning system.
