Can you help with sore lump at base of implant following PIP rupture & replacement?

I have had my last breast surgery 9 years ago , after having pip implants and a ruptured left breast I had them removed and replaced. I noticed a lump in my breast that appeared a while after which has grown. I had it checked and my surgeon didn’t seem concerned. Now the lump is protruding out my skin and has grown and last week turned extremely sore and a red ring around it. It is right at the bottom of the implant. I’ve been prescribed antibiotics for now but feel I need a scan and worried
