Swelling after calf implants

I had calf implants done in 2001. The left leg has always been more swollen but now it's become very visible. There is slight pain and it feels very hard where the implant is (which is not silicone, but rather a firmer substance). I've been to a cardiovascular doctor to make sure none of my arteries/veins are being compromised. I've also been back to the original doctor who had done the surgery and she doesn't have any suggetions/solutions for me. She is a Board Certified doctor. What can be done about this? Any suggestions would be so much appreciated.
