The swelling you are experiencing in your legs and feet are more than likely secondary to where the fat came from as opposed to the BBL.The farther down the leg the fat is harvested from, the greater likelihood of swelling and bruising all the way down to the feet. The asymmetric nature of your swelling is common, and in fact, symmetrical swelling would be very uncommon. Wearing compression socks and garments can be useful. Unfortunately, pressure on the lymphatics (system that brings fluid back from the lower extremities to the heart) from the BBL, etc. causes fluid to be driven back into the tissue leading to the swelling you are experiencing. If you were my patient, I would recommend 20 minutes out of every hour, you lie down flat with your feet on several pillows above the level of your heart. This will allow gravity drainage out of the lower extremities leading to less swelling. At this point, it would be appropriate for you to get in touch with your Board Certified plastic surgeon to see what he or she recommends for your lower extremity swelling.
