I've recently started running again after a long absence from the sport. After running approx 1 km, the skin on my thighs start itching uncontrollably. So bad that I have to stop completely.
I have to resist scratching it, because if I do, red marks apear on my skin, and stays there for the next few hours. If I don't scratch it at all, the itch goes away in about 2 minutes.
My doctor doesn't have any idea what it may be. Is this common amongst unfit people? Since my mom also has the problem, i'm thinkng that it might be a hereditary skin condition.
Anybody out there fimiliar with the condition?
