Only the plastic surgeon who performs your BBL can answer that question as he/she will know of any complications in wound healing. The first 3 to 4 days tend to be the worst for most BBL patients. Many of my patients feel well enough to return to work at 1 week, but some patients may need 2 weeks before returning to a SEDENTARY job. At six weeks, they can return to strenuous exercise. During the first six weeks after a BBL, sitting is to minimized. Because you have to drive (be sure to use your pillow) eight hours a day, it is critical that every 30 minutes or an hour you stop, get out of your vehicle, and stand for a few seconds to take the pressure off. This reduces the chance for fat necrosis. After 6 weeks the fat has revascularized, and you have a very good idea of your final results.
