For aftercare from your procedure, you will be asked to avoid prolonged sitting for about two weeks. This is very important because prolonged sitting will damage the fat. You will also be encouraged to sleep face down or on your side. When you do have to sit, you will have to use a pillow or cushion placed behind the legs (hamstring muscles) to help raise the buttocks, avoiding pressure onto the fat grafts. You can generally resume exercise after six to eight weeks.
