pin point red dots under skin in small patches that arent always there.?

They are in 3 places that ive noticed so far. One was on my arm bicep inside area. It was a small cluster of tiny pin point red dots llike 6-15ish that were under my skin, smooth to the touch. And if I rubbed my skin, everything would turn white but the red dots were still red and clear as day. the other places are on the pinky side palm lower corner towards my wrist but not quite... they werent their earlier today and i was trying to show a PA so they could look at it, they said it looked like i might have a rash just in general my hands are kind of red and skin is cracking / flaking alot, but that if it didnt bother me i didnt have to go to sick-call (military) to get it checked out. then later that day after I left, i rubbed my left palm area and felt a slight pop and noticed the bunch of red dots on that palm, where as the day before it was my right palm. They go away after a few hours but it seems to keep happening. Any idea what it might be? Petechiae sounds like what it is but not as much as you see in most pictures .. small clusters about | | big (not the dots just the cluster in general) they dont really itch or anything.
