For the last fifteen years since i was a freshman in high school i develop a terrible itching on my entire body when i get hot. This only happens in the winter time making me hate the winters. I dont get rashes or break out. I itch on my back chest arms and head.. It allmost feels like my skin is stretching and causing me to itch. IDK. I have tried putting moisturizing lotion on my body every year and it doesnt help... everyone says dry skin .... i also take warm showers in the winter because i know its not good if you have this problem...To really describe it when it acts up i could just keep scratching till im bleeding and it still feels good. the only way to calm it down is to cool down my body usually by stopping whatever i am doing at the time.. I never had this problem untill i was about 13 yrs old...
