I have a ewe who jiggered her hips prior to lambing - probably butted by another. I kept her in and she duly lambed 4 days later, but was reluctant to rise to feed her lambs. I went to the vet, who prescribed Metacam injection (used for cattle) 2.5ml/100kg every other day. Although still very slow, she is in a more comfortable condition and managed to shuffle around the field with her lambs today. I'm hoping she will be able to rear the lambs, then make a decision on her future. So Metacam is available as an injection for sheep.
Not every day is baaaaad.....
