This is a type of arthritis that affects more than five joints. Normal arthritis can be just in one joint, whereas oligoarthritis is inflammation in two, three or four joints.
My husband thought that poly arthritis was arthritis in cats! For this reason I would like to put the record straight.
As we know, there are all different forms of arthritis. The most common form is like a degenerative type, which is the one that grandmas normally get. It comes from general wear and tear on the body and is called osteoarthritis. The pain comes from the wearing down of the cartilage in the joint which normally acts like a cushion to provide comfort for joint movement.
I remember when my mother fell over when I was about 10 years old, slipped on some ice, anyway she ruptured a disc in her back which meant that the two bones came together with no support in between. Even though at the time I thought it was hilarious, I now realize that the pain would have been pretty bad and quite unbearable at times. All the thoughts of the grinding bones put my teeth on edge … more grinding!
Anyway the other common form of arthritis is called Rheumatoid arthritis, however this often occurs in much younger people as this is an auto-immune disorder. It is this type of arthritis that is most often present with poly arthritis.
The best treatment for this type of arthritis is a firm mattress, a flat pillow, plenty of rest and take copious amounts of omega 3 oils and glucosamine. The more lubrication you get to your joints, the better.
I hope this helps to clarify the difference between the different forms of arthritis and poly arthritis, even though cats and dogs for that matter contract arthritis just like us, after all they are mammals too, poly arthritis, as the name suggests, just indicating that many joints are involved, so the pain would be pretty intense and spread out.
