Sorry to hear about Grace - but she will get better. I know someone whose endurance horse did exactly the same thing a couple of years ago. He's 100% better now and back competing.
We are in East Yorkshire so would only be good if your horse needed a course of treatment but we can provide a small super place for horses at a very competitive price. I have sent you a pm with further details.
As someone has already mentioned Higher Spen at Fence cater for that sort of thing. I took Jethro there at end of September to use their Panama Spa. They also have a swimming pool which will be great for exercise after injury.
