My cat screams when she stands and tries to move

My cat screams when she stands and tries to move. Could it be a urinary problem or a nerve problem? Any other problem?

My cat is a 12 year old Calico named Baby. She is a sickly one anymore and I really do feel bad for her. But lately she's been having problems that I've never seen before in a cat. When she stands she screams or cries, and when she moves afterward, it seems like its with great difficulty.

My sister took her to a vet, so I'm not sure what was said about it. But I would like to know what is wrong, please help if you can.....

Other symptoms:

screaming
tail hanging down at odd angle
kicking legs out when lying down
laying with back end in air, almost like she cant put it down.
flopping from side to side right after lying down
walking is stiff and legs seem to be kept straight (if that makes sense)
can't stretch out without screaming and yowling

There are others but I don't know how to describe them....
