I Am On Anastrozole (10 Days) Following Left Breast Mastectomy,

I am on anastrozole (10 days) following left breast mastectomy, chemo, radiation. I am itchy on my right breast, right upper arm, left upper arm, under my chin and part of right chest. Surgery site is healed but also itched (as part of healing?) Does not seem affected. Will call my PC about this. How can I relieve the itching meanwhile?
