You might also check with your oncologist about switching aromatase inhibitor. I was started on anastrozole and could barely get up to walk, the pains was so significant. From there I was switched to letrozole and still had problems, and finally switched to exemestane and have been doing well with that. I walk daily for exercise. As far as the hand swelling, it could be a type of lymphedema known as axial webbing which can be helped by a physical therapist who knows about lymphedema and lymph massage. I have had repeat bouts of this following surgeries and radiation and that helps considerably as well as using a "swell spot" which the PT ordered for me. It's used under your bra and helps break down fibrosis in breasts from radiation and softens the area. All the beset to you.
