Do not itch it once you get out of that cast! I broke both my arms about 9 years ago at the same time believe it or not. My arms/wrists were so itchy by the end of the 8 weeks that I couldn't wait for that cast to be off. Well they took it off and I just started to rub them not even scratch and the skin was so tender and soft that just the running alone caused the skin to start to fall off and I look down and notice blood all over my arms, hands, and dripping on my pants. Lessoned learned with that. Once you get those off don't scratch! Hopefully you will heal soon!
