If the kyphosis is new, I would be concerned the symptoms are related. since Nutmeg is not responding to treatment, I recommend to preform further diagnostics. Based upon your description, I would be concerned Nutmeg has abdominal pain, spinal pain or perhaps pressure on her internal organs.
Top differentials include:
pancreatitis
hepatitis (many potential causes)
foreign object in gastrointestinal tract
intervertebral disc disease or injury
internal abscess
fluid in abdomen
tumor/cancer in abdomen

Some potential diagnostics including imaging (ultrasound would be preferred over x-rays), bloodwork and a blood test specifically for the pancreatic enzymes like a CPL.

I hope this gets figured out quickly and please feel free to post any additional questions.
