Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
Any chance of a fall or trauma?
Any gagging, retching, lip licking, drooling or vomiting?
Are her gums pink or pale/white? Moist or sticky?
Where were you pressing when she cried (ie belly, back, hips, etc)?
Could she have eaten something she should not have (ie bones, toys, plants, chemicals, etc)?
