Don't worry; you aren't alone on this problem. It usually occurs during exercise performed after a long period of inactivity. The itching is not on the skin, it is inside the skin.

You see, there are millions of tiny capillaries and arteries inside our muscles which expand rapidly due to the demand for more blood that is brought on by exercise. When our bodies are sufficiently fit, these capillaries remain open allowing maximum blood passage, but, when unfit and inactive, they tend to collapse, allowing only minimal blood passage (which is sufficient for a sedentary person, however). The rapid expansion of these vessels causes adjacent nerves to send impulses back to the brain which are interpreted as an itch.
The problem should go away once you have increased your fitness level.
