I had fat transfer to breasts. A cup to B cup. I wanted to know how long i need to wait until i can start working out again? My doctor tole me 4 weeks. I am on week 4 post op, but I feel that is too soon, Will I lose any of the transferred fat once i start to workout again?? I am a runner and heavy weight lifter. I workout 5 days a week approx 2 hours a day. Should I start easing back into working out?
