Really hoping we're not back to square one

I took Grey to the vets today for his nails to be clipped under sedation. They'd got really long through the lack of exercise and he just won't let me near them to cut them without a struggle. When I picked him up he was limping. By this evening, he's limping as badly as he was over 6 weeks ago. I've called the vet back and he's on Metacam for the evening. I'll see how he is tomorrow.

I'm worried in case something has happened and he's back to where he was. I was only saying this morning how much stronger he was in his body movements around the house. Damn.
