I have made a couple calls with no luck, nobody is willing to tell me ANYTHING or where to get help

I even called the Humane Society and she won't tell me anything, she said they are not allowed to say anything about vets, or where to go or anything, she said call around yourself. Ugh how rude and disgusting! I am not so worried about her knee's. She doesn't do too much jumping or climbing stairs. She has had her rib cage broken and it fused together wrong, you can hear a click and feel it when she breathes. The vet told me there's nothing they can do about it now. I don't know if it's uncomfortable for her or if it causes her pain. She doesn't have an ear infection, she had some redness but the vet said it was nothing serious and gave her some drops. She has been on antibiotics now since beginning of December. She has been given shots, pain meds and antibiotics. It doesn't seem she is "better". Right now I can tell she is in some pain but I don't know why or from what. The vet who looked at her is not in til tomorrow. Her eye is totally better, you can hardly see any red in it so I am not so worried about this. The only thing I know about right now is that she has a couple baby teeth and her teeth are pretty bad as in they were NEVER taken care of before until I got her now. So I don't know if they are worse then I think and causing her pain. Or what ever else it is. I am just frustrated because I can't even get a recommendation to a good vet from anyone here

I don't want to give her up, it will be like I am giving up ON her. I know this is probably a really stupid question but what if I did give her up to a rescue? And they helped her, could I possibly adopt her back?

I love my baby

She was 4.3lbs at the vets last week.
