It's looking like things are going the same way this year. The big difference is that last year, putting her shoes back on made her much more comfortable pretty quickly. She's already got shoes on now so that means of making her more comfortable isn't an option. I don't know if what we have going on this year is due to concussion/stone bruising, which is certainly possible - the fact that one front foot is much worse would indicate that - or due to something about the grass - we've been out for a while now, but she's a big eater and has obviously been gaining weight. (My farrier's comment yesterday was that she didn't look like she'd been on a diet - nice! - can we say "fat"?). The spring last year was consistently much colder and wetter than it's been this year, which could explain the one-month timing difference. Once she went back out on grass, she was fine, which made it seem like it wasn't the grass that was the issue, but I'm not so sure. She's been at our barn for a number of years now, and last year was the first year she'd had any problem of this type, although she's always had a tendency to sensitive feet and weight gain, both of which can be signs of insulin resistance.
I did put her out to pasture this morning, and also gave her a gram of bute for her discomfort. We had frost overnight, and sun and much warmer temperatures today, so the fructan levels in the grass will be high this afternoon - I'm going to go look at her early this afternoon and possibly bring her in (although she won't like that much). We have really lovely pastures, with appropriate grasses, but it may be that Maisie can't tolerate this much grazing. I've also upped her chromium/selenium/vitamin E/magnesium supplement (for insulin resistance), which may also help. If she needs to be on dry lot, I don't have a lot of options - we don't have a permanent dry lot, although perhaps we really need one - our big dry lots have been reseeded. She could share Charisma's paddock, but that would mean she wouldn't be able to have hay, and with her history of ulcers that wouldn't be good.
Poor Maisie - can we say "high maintenance"? I'm just hoping she feels better today, otherwise I'm not sure what we're going to do. I'd hate to have to move her to another barn, and would only be happy with one where the horses had stalls opening into a paddock so they could go in and out at will, or a place with other good all-day turnout options. Movement is probably good for her, but spring grass may not be.
