I am so sorry your fur baby has this trouble.
Things that come to mind are arthritis, a disc issue, hyperthyroid and injury.
She should be started on an anti-inflammatory like Onisor:
Canned food is excellent for arthritis as is a glucosimine supplement:
Weigh loss can be caused by hyperthyroid.
If she has this ailment it can be treated with medication and a special food. It is made by hills and called Y/D. It comes in wet and dry forms:
You would need to do an MRI to diagnose a disc problem.
Make warm packs by adding raw rice to old socks, tie the top and warm in the microwave. She can also lie on a warm heating pad.
For pain, I recommend a feliway patch so it does not go through her stomach.
Please let me know how she is doing. Reply here or if you prefer we can speak on the phone.
I hope this helps her feel much better.
Please be so kind as to rate my answer with positive feedback; that is the only way I receive credit for my assistance. Thank you very much!
