Infection after breast lift

I had a breast enlargement and lift in October 2017, then a small revision lift in March. Since then I’ve had an infection in the left breast, and now I have tissue coming out of my breast. Apparently this is OK and will heal, despite me telling my Drs PA that I’m not happy and that the wound is getting bigger. I’m on a 3rd set of antibiotics-so I think the infection has gone, but im not happy with how it’s looking-is this normal? Do I need stitches or will they not stitch because of the ‘infection’?
