The not knowing and worrying is awful, even more so I imagine when you're making such a huge move north aswell, I really feel for you Laura and I so hope Kevin is ok. I'm sure you've already investigated but everyone always suggests rockley farm with regards to lameness, or maybe have a look on the Phoenix forum if that's what it's still called. I asked about lameness on there when I had issues and I'm sure it was nic from rockley who confirmed my thoughts.
If you want to vent just drop me a pm, and have hope, remember me having to take blondie to the dick vet, I was a total mess, I really started to understand what mothers must feel like when their children are in hospital, and we came good. Yes it may mean an adjustment in your expectations but it's generally never so black and white as we worry it could be. Big hugs x
