I have silicone breast implants for 11 years, had 2 babies and breatfed without problems for 2 years. I have lost a lot of weight after pregnancies. Now my right breast feels a bit lumpy but no pain. It is like I can feel my implants more than before but definitive some lumpiness close to the nipple and on the edge. My right nipple seems to be lower than before pregnancies also. What should I do?
