I'm a 67 year old male in pretty good shape and this just started happening to me recently. Assuming one can't distinguish between a fierce itch and pain, I suspect it has something to do with changes in circulation, maybe diminished capillary circulation.
I get this quite often. I think it's hte build up of sweat and heat which irritate the skin making you want to itch all the time. Once you cool down or apply cool water to it and dry yourself it tends to disappear.
I have heard of this before, and I believe it is to do with your levels of hydration. As you sweat your body looses water. As water levels decrease the sweat becomes more concentrated in an act to save water. This means that all the salts etc in sweat are now more concentrated on your skin. To solve this (or just improve it) try drinking much more water whilst jogging. Hope this helped =)

It's called vibratory urticaria. I have this condition as well and it's not only frustrating but sometimes painful it itches so bad.
