Working in the medical field, I don't see this as a "true emergency", life nor limb at risk. She's exhibiting no signs of pain... except limp, yes, that's pain, she's not holding her foot up and kicking with it, like she would do if it were hurting really bad. No infection, it's not going to kill her, she's not going to loose her foot (or so it looks to me), so I think it can wait until my afternoon off. I know everyone is different on what they deem as an emergency. She was trimmed about 4 wks ago, first time since I've had her, and I don't like the job he did, so I really don't want to call him out.
Years ago, I had a horse who cracked open the heel of her hoof on a rock, vet just had us do what I did to her today, so I'm not worried about getting to the vet NOW... But, she will be going to the vet, and if it looks worse tomorrow, I will take off work and take her then.
