Weird muscle thing happened to me today...

This may be a common occurrence, but I've never experienced it before. Do you know what this is?

I just started working out with a trainer. Wednesday was my first session, and my quads were pretty sore today (DOMS) at my second workout. We did a circuit that involved my sore quads quite a bit. I was right in the middle of one exercise with quads burning more than ever, and all of a sudden they just got really hot. The pain kind of went away (temporarily).

Any explanation? Enlighten me, please!

I often find when I workout sore muscles that the pain goes away.
