| OP here: For me, it's definitely the parts that are jiggling that get it. I'm pretty sure it's the opening of blood vessels; just want to know why…is it a release of toxins that have been trapped or accumulated there due to a long time of non-dilation? |

Used to happen to me. I think I read an article that it is an allergic response and a hot bath or shower before exercise will prevent it. (Who the heck wants to bath or shower before running?)

| This happens to me too. Coincidently I suffer from exercise induced asthma. I heard it was a lactic acid buildup being released, which improves with consistent running ( I never seem to achieve that state). But, I will try taking allergy Meds beforehand. |
