Sometimes when I do brisk walking my legs itch like crazy. When I scratch it loo!
Question:
Answers:
This happens because, when walking all the blood comes to the surface your skin. THis is the way your body cools itself. Therfore, when you scratch, it will look like a rash becuase there is a lot of blood right next to your skin. Also. the increased amounts of blood will make your skin more sensitive, which can cause sensiive people to feel itchy.
Allow youself to cool down, will cause the itch and the Rash should go away.
