This has been going on for a long time. I have experience
itchy legs whenever I am walking or running, it's so bad that I have to stop and itch, and I get these red marks all over my legs. Today, I was walking and had an itch so intense I nearly cried, I nearly clawed my skin off it was that bad. And it would not stop for ages, even when I stopped walking, I also noticed my hands shaking and I literally broke a nail or two itching my legs.
