I brought her to the vet on Thursday morning after she screamed out in pain on Wednesday night and would scream when I touched her. After a physical examination and xrays, the vet suspects she is probably hypocalcemic, based on how faint her bones looked against her organs. A blood test was not done to confirm this. However, the vet says she is able to see some "fractures" on her spine, along with some bone chips, one of which is close to the spinal column.
She is home now and is on Prenisolone, Clavomox (antibiotics), Daneuron (nerve supplement) and also calcium gluconate. There is no pain killers as the Pred should help with pain control. The vet says the situation is "salvageable" (since she is still so young - 3.5 months), unless it turns out to be something genetic. That would come with a very grim prognosis.
Tutu is now confined in her cage and only allowed out to walk under close supervision (she is not allowed to jump or run around). She still has some discomfort but is able to get up and take a few steps (she couldn't stand last night). She cries when I have to move her.
If anyone has any experience with this, please do share. I would appreciate it very much. As you can imagine, I am a total wreak. :(
