I know I'm really new here but I thought I'd chime in just because I have a little bit of experience in this... I had a Chinese water dragon with osteomyelitis in his lower jaw. It can be a serious infection but once it's treated with antibiotics and the infection is gone, I agree your BP might still have that swelling around her ribs. My CWD still had lumps on his jaw long after the infection was taken care of. My vet said it was calcified scar tissue.

I would second getting a culture done because it took forever to get the right antibiotics for Jazz ^ here and he suffered long for it.

Don't take my word for it because I have basically zero experience but I wouldn't put stress on her by breeding her when she has had an injury like that, regardless on whether or not it's genetic. I wouldn't want to risk her carrying eggs, myself.
