Red pores/rashes on leg. spreading on another leg. is it chicken pox?

Doubt it: Cpx is a rash that generally starts around the neck and face before spreading elsewhere.The pox starts as a small bump that quickly becomes a blister about 2X the size of a BB shot ,ruptures and begins to dry all in the space of 12 hrs.They come up in waves of half a dozen or more.Your description does not bear any resemblance to this.
