Hi Doctor. For the past few days I have been incredibly itchy on my arms, stomach and sometimes my legs. I live in NYC, so it's cold and I tend to shower often (1 - 2 times a day), but I've never had this much trouble with my skin. I now have little bumps on my arms from scratching. any help would be appreciated. Thanks. Ivy Herman. I'm also a bit nervous because a friend was diagnosed with Leukemia and her one symptom was a rash. She is a personal trainer in great shape. Scary. Thanks so much
