Within a few hours, she'd lied down and we couldn't get her to stand so I called the vet and he found a big abcess in her sole (also commented on the fact she was walking on her soles) and cut it away. It was full of puss but the relief was immediate and after a couple of days she was no longer lame.
We're still poulticing (gunk still coming out) daily and while she doesn't bother, we've had a set back as the tape i'd been using ran out and after using another type (all horsey stuff supposedly fit for the purpose), it came off overnight and she'd managed to pack the hole with muck etc.
A good scrub and soak later and we're back on track but we've still got goo coming out although she's sound now but my problem is that it's been very hot here and she's sweating in the wrappings i'm doing and the heel bulb is now very soft and almost soggy and light grey in colour.
I can't stop poulticing and wrapping etc and if I don't wrap good enough it just comes off and we end up with it being yucky and packed with poo etc, but will it cause her problems with the heel bulbs being soft or will they dry up when we finish wrapping.
It looks as though the abcess has blown out of her hoof wall too as she's a small hole there (but that's obviously covered at the moment with the wrapping we're doing) but is there anything I should do to that?
