Get the vet out yesterday.
It sounds like there is multiple issues that need to be addressed. If she is limping, she will be in some amount of pain. No swelling doesn't mean there isn't anything there.
Vet to check out leg, back and do a worm count minimum to see why she has either a large/swollen stomach. Check out leg and back area. After that, check saddle fit and have a chiro to look at her back.
Just my opinion.
