Glad you got some answers!
I mentioned in your other post, but I did indeed have this in the past (although not when I was pregnant). I had it for what seemed like months... It started near the side of my rib cage and spread along my stomach/torso and on my back, with a few on my neck. Mine did not itch...
My doctor told me that sunlight can help clear it up and told me to go tanning a couple of times (I did) and that was actually the only thing that ended up helping.
Hope it clears up for you soon!
