Silicon Chin Implant. 3 weeks after swelling went down, face swelled up again. Assumed infection. Went on antibiotics. Swelling went down as expected but incision began weeping "puss" which was swabbed and analyzed. No anaerobes or aerobics. My surgeon is convinced I am one of the .01% that has an allergic reaction to silicon. I refuse to believe that. weeping continued until i took antibiotics for 3 weeks. incision healed. Weeping stopped. Month later, pocket at incision site forming again.
