I am 13 days post op from my Breast reduction! The first week was rough but tolerable! Is this normal? (photos)

I am on my second week of recovery. Things have been good and I am actually already back at work but I am now having some pain on the sides and it feels rock hard. My stitches will come out this Friday. I am just pretty surprised by this pain since the first week went so well. Is this normal?
