Is this normal after double mastectomy?

Thanks for your responses. Thing is I felt I was moving forward until Sat morning when whatever this is started to set in. That's normal. Things like to flare weekends! That's when things like a tooth abscess declare themselves. And yes my own research brought up cording. In theory I may be able to see it or feel cording but it's both sides and difficult for me to see or feel. Doesn't help to have saggy upper arms from big weight loss years ago. Now getting occasional stabbing under right armpit. Shall phone breast care nurse this morning when they arrive at office. But review at hospital tomorrow anyway. Sister - unsuspecting chicken and you lol. Punching a pillow may have hurt you too, but I think chicken more satisfying. But I do have image of whole chicken and rolling pin. What's the recipe?
