Is my body rejecting my calf implant?

I recently had calf implants. My left leg is perfect. No pain and the implant has softened and looks natural. My right leg has quite an issue. The implant is hard and swollen. It has a lump at the base of the implant and the lump has pain. I have been to many medical doctors and they all say that the lump is not an infection as the white blood cells are too low. Can u tell me what to do?
