Hello, I turned 18 on the 9th of May and about 2weeks after that I have had non-stop itches on my knee's. It has spread since then to my arms, feet and hands. My hands are the worst so far because the itches are so strong I've started scratching them with my mouth. Small bumbs have appeared on my hands aswell where the itching is. When I scrach with my mouth I tend to burst these spots. Below are two pictures of where the spots are located and what they look like.   This is just one spot on my left hand. https://dl.dropbox.com/u/70891398/2012-06-22%2011.55.03.jpgThisi is a group of spots on my right hand that are in between my Ring finger and little finger.https://dl.dropbox.com/u/70891398/2012-06-22%2011.55.18.jpg
