Both my mother and dh have tinea versicolor. It's a yeast/fungus skin infection. My dh used to get them on his arm, now it's mostly his trunk and back. It gets worse when he's been sweating a lot. Kombucha tea takes care of it, as well as antifungal topicals and medications.
I've tried looking up all sorts of rashes online but everything I find that remotely looks like it says it's either itchy or raised. Which it isn't. Soooo... I think beyond checking with my mw on Wednesday I'm back to assuming it's due to increased blood flow (like red palms and soles of the feet) during pregnancy.
I think I may also have what you are talking about. I am 5 months pregnant and just noticed these small red dots all over my arms and hands. It looks as if someone took a red faded sharpie and poked them on me. It looks like a bunch of beauty spots. They are not all clumped together, but spread out. No pain, itching, or raised bumps.I've looked this up online and can't even find pictures close to it. Please let me know what you find out. I would really appreciate it.
You described exactly what I have!! I have been searching the web trying to find what it is as I am only 7 1/2 weeks and won't be seen for a few more weeks yet. Please let us know if you find out what it is. Thanks so much! Audrey
