So not really poop related but I didn't want to make another thread

We ended up back at the vet because I wasn't seeing much improvement - thankfully, an x-ray of her back and hips didn't show anything.

He doesn't think she is showing pain; she let him lift her and move her around for the x-ray. She doesn't show pain when I pick her up either.

The vet's diagnosis was age and fatigue.  Sigh.  He thinks the restlessness at bedtime is because she is anxious due to age and she's starting to get cataracts; obviously not being able to see as well would make her more nervous. 

I also blame myself (I know, I know) because I hurt my knee and we were not able to do physical therapy as much at home (plus, one of the recommended exercises she was not really able to do).  We were also spending a lot of time together, making her separation anxiety worse when we're not.

For instance, I took her to work for two days in a row but not today - when I came home, she was having a lot of trouble getting around because she paces and worries.  I have her gated in the living room with pee pads (which she has used) so she's not stressed because she has to go, she's stressed because I'm not home.

I just feel like she can't get better because inevitably she has to be alone; I worry that taking her to work every day will only make the separation anxiety that much worse when we're not together.

I'm going to contact the physical therapist about an appt for a new plan for at-home work and to get her back in to use the water treadmill.  I can only get her there once/month so I hope it helps.

Thanks for listening everyone.  If anyone's had this kind of thing (single limb weakness due to overuse due to stress that I can't control) I'd love to have tips, anything...I'm sure my girl is feeling my stress as well.

She's still perfect though
