Sorry - should have said I was back playing golf within 3 or 4 MONTHS! Don't want to give the impression that I'm Superwoman!
I don't know how relevant my experience is to yours, but maybe it will shed some light on the recovery etc. I had a single mx with immediate LD flap recon in 2014. The scarring on my back is low down and I can wear an M&S "tummy control" swimsuit without the scars on my back showing. As to the front, the skin from my back that was used is slightly darker than the breast skin, and I opted not to have a nipple recon or tattooing, although the scars do show still. Recovery was not too long, but do persevere with the exercises as it helps, and I was back playing golf within about 3 or 4 weeks. You will be advised not to do any heavy lifting on that side for some time as it will upll on the stiches. Good luck.
