I had a Double TRAM flap reconstruction in Dec 2013. One was a delayed recon and also a propylactIc with immediate recon. I went back to work 16 hours a week at 6 weeks post op. Now 7 months down the track I wonder how I did it. I had issues with groin pain relating probably to where they took my stomach muscle and put mesh in. I despaired that I would ever be able to stand for more than an hour straight as I sometimes have to as a nurse. I would say it took me around 5 months to really be on top of that. I had however done chemo twice in 18months and radiation ( I had had a recurrence ). Whilst I still get tired at times I think it is more to do with two diagnosis in 18mths and all that treatment and not just the surgery. Everyone is different and I guess if you were fairly fit before that you will bounce back a bit quicker. Be kind to yourself and listen to that body of yours. Rest while you can. Even without chemo/ radiation you have been through a lot.
Hang in there, it does get better.
