This is my second elongated which i acquired after a friend bought her from a rural village market a few months ago.
She is doing really well, but she has had a hard life. You can see the shell trauma and where it has healed.
Another thought would be to locate an expert vet here in the US or elsewhere that can provide guidance to the less experienced vet and communicate through a translator via phone. Medical translation services are available in any language. I use them with my profession on a daily basis. You would have to pay the expert a consult fee which would add to your costs but having an expert to advise the vet service you have available would be well worth it. I know I am late to respond but new to forum and reading some older issues. I hope things have improved for your little one.
