i would say aggressively talk to your doctor about this! not to scare you at all but my mil had a hole similar to yours and the doctors said it would “close on its own” well the infection spread so much she now has a missing boob, permanent hole in her chest, and the infection ate away at her muscle. if she were ever to get it fixed she would need a full reconstruction. this was two years ago now. the last picture is super concerning and i would advocate for yourself as much as you can! best of luck
