I never experienced itching per se, but I’ve always had tingly, twitchy, jumpy feelings, especially after particularly intense workouts. It does appear to be circulatory, and from what I can gather, very common. Just your body standing up and taking notice of the wonderful things you're doing for it. Keep it up!
I have been having the same problem but on my mid section between belly button up to under my chest...i think it is maybe also my skin tightening a lil or re arrangeing itself or also the exercise, either way i feel like i want to itch it off by the end of the day ha ha ha
