I have mentor silicone implants, could i be allergic to my implants? I have rash hives on the bottom of both my boobs and it is spreading around my boob going up a little more. I am very scared, I am 3 weeks post op and the rash became more apparent week 2 until now. I had texture silicone implants before and I was fine. I'm just scared I am allergic to my implants and that this rash/hive will not go away. I put cream on it but it's not going away yet.
