So sorry to hear that you continue to struggle with radiation dermatitis. It is a common side effect and can even return much later (called radiation recall)... ugh. Firstly, keep that area free of cologne, anti-bacterial soap, soap in general (ask your pharmacy to order Aquanil Cleanser or Lotion, or CeraVe Hydrating Body Wash), and use clothes detergents which are free of scents and other additives (look for or order Tide Free & Pure or All Free Clear.) Also, keep the area moisturized with something which has no chemical additives.

As for the anastrozole... I agree, it's a bummer. I opted to take just half a dose and I still experience aching joints and bones (and I don't have osteoarthritis!). It worries my oncologist (the half-dose), but I remind him that recurrence also increases after taking an AI... it really is a no-win situation in my view. We each have to pick our way through the therapeutic brambles. I wish you the best outcome and, at least, calmer skin.
