For the past two weeks, my cat will on and off limp her back legs. One day she will be limping on the right leg, next the left. Then she won't be limping at all. Sometimes she will limp and then kind of fall over and lie down. Then the next minute she is running like a mad cat. She is an 8 year-old Tortie/Calico. The vet did a series of blood work (why I don't know) and found nothing wrong with her. She also appears to have symptoms of a cold or upper respiratory infection. She does not have any thick mucus, but it is slimy when she sneezes and she rubs it on me. She's been sneezing for the past 4 days. I checked her paws and didn't find any sores or anything on them. The only think I could surmise was that she has arthritis in her hips? I'm at a loss.

I would suggest having your vet check to see if your cat has a saddle embolism, which is a clot in the abdominal aorta, where several blood vessels branch off.
