This is why a video even beats a picture for diagnosing.
From the side, she looks " normal". From the bottom however, she's obviously not " normal". This could be eggbound or the beginning of Dropsy.
If you can get antibiotics where you are, I would start her on Kanamycin ( Sold as Seachem's Kanaplex) or Minocycline ( sold as Maracyn 2) in a separate Hospital tank. ( Because your Ph is 7.0, if you can get Nitrofuracin Green, a Kanamycin/ Nitrofuricin green combination will be a more broad spectrum treatment.) In the mean time, start her on Epson salt baths to try and relax the muscles. If she is eggbound, that can help her be able to push out the bad eggs. If it's dropsy, it can help reduce the swelling. Either way, the antibiotics can help address any bacterial issues that can arrive from being eggbound or organ failures in the case of Dropsy.
