This does not really answer your inquiry, but.....I had bilateral mastectomy with diep reconstruction last summer (2020). That was pretty lengthy surgery. It was a piece of cake. I had very little pain. It took the wind out of me and I was moving around pretty slowly, but was back up to speed in about a month. I was very careful about moving my arms and I protected my stomach area where the tissue was harvested from. My experience was no pain and tiredness probably because of the extent of the surgery. I did get up and move around while in the hospital and when I got home. I get tired of laying around. I got up and walked around outside of my house...just kept moving. Take it easy and follow the doctor’s instructions and you should be recovered in a month or so. You will be fine and I wish you the best.
