Help to diagnose

[Mega]

Help I'm very worried.
My mare had a foal in May. She lost a lot of condition, the foal was growing v fast so had to be kept on restricted grazing. Weaned them 17 Nov when my mare went to my neighbours. Where she has been turned out 24 7 (rugged) on very good pasture. I've also been feeding her twice a day. She was just starting to get back to her former weight and looking well. I've been riding lightly for a month or so (hacking a couple of times a week) then last Wednesday she was hopping lane in the afternoon. When I brought her in there was no signs of anything untoward apart from the she was very lame behind. We brought her home where she has been on box rest since.
The vet came on Friday morning and to my shock diagnosed laminitis (she's 15 3/4, I've had her since 9months old) she's never had it before even when over weight. I'd assumed she'd hurt herself in the mud (it was very deep near the gate.
Anyway she has been on laminitis rations since Friday and bute twice a day. She is still very sore behind and makes minimal movement resting one then the other hind leg. I'm very concerned as not only has the lameness barely improved but she now looks evacuated.
I've spoken to my farrier who is coming to look on Thursday but also doubts laminitis and said I'll talk to the vet once the farrier has been with view to him returning on Friday if she's no better.
Any ideas what it could be or what to do for the best? I'm so worried for her both with the pain in her feet/groin area (I'm not sure which) and her weight.
Thanks in advance xx

Sure it's not an abscess? (or two!).

Had two hind feet on one horse at New Year, I thought she had a neurological issue as walking on her toes on both hinds.

Then in my other horse I've had one in each left foot, also at the same time!

Both resolved and back in work.

Has she frog supports on ?
If not I would .
And it would not be the first or last time a couple of abscesses got diagnosed as something more serious .
However if there's any chance it's lami you must proceed as if it is lami .
Feed the foal , weaning ,going on to good grass cold weather hard feed there's a lot going on that points to lami .
What's her digital pulse like ?
And honestly if your worried I would get the vet back sooner rather than later .

I can just about feel the pulse in her front legs but not in her back ones. I will get farrier to come tomorrow. I'm most worried about her weight as the lameness isn't getting worse if anything it may be getting slightly better.
