Mystery lameness

I have had my new horse for 10 weeks. She is 6 years old was bought from the field, barefoot and unfit and has done very little work in the past. She has been turned out with the intention to start light hacking in walk, building up to schooling by the time winter comes.

After 4 weeks (without riding), she was lame most notably to the left. My vet and farrier suggested bruising of the sole, especially since she had been hairing around a little as she got used to her new home. She was rested and came sound within a week or so.

We started ridden walking every other day. Whilst observing her in the field one morning I noticed that she seemed pottery and unwilling to move freely down hill. The onset of this was fairly sudden (fine the day before).

The vet came the next day, she trotted up 2/10ths lame and the vet confirmed that the lameness looked footy, not laminitic and applied hoof testers (which gave no reaction). There was also no visible bruising to the sole (yet), although the vet advised to work on the assumption that this was the problem for now.

My farrier put two front shoes and pads on, again no reaction from the hoof testers.

She is turned out in a restricted, level paddock. When trotted up, she displays the same degree of lameness as she has for the past week, although when getting a bit excited in the field last night, she looked sound as anything, after trotting for a few minutes she went back to looking incredibly lame. She is worse when turning and gives the impression that her feet are tender. My farrier has been to look at her quite a few times since the onset of the lameness, commenting that although it is usually the near fore that looks affected, the off fore occassionally looks worse.

My question is, what are the (more serious) alternatives to it being bruising? The lameness can be described as intermittent. Although there is no swelling or heat in the leg, the feet are cool, on a couple of occassions she has had a slight puffiness around the fetlock of her near fore (which is gone the next day).

Obviously I am concerned that there is some more sinister ligament damage or similar. Since it took her a while to settle, she has spent some time flying around the field at top speed. With her lack of condition, I worry that she has done some serious damage.

Any one have any ideas???? I know it's a ridiculous question, and could be absolutely anything.

It is worth stating that she was 5 stage vetted before purchase. She came with badly balanced feet, but had not been lame at her previous home in this way (I am confident of her history).
 
Time for a lameness work up, I'd say. It could be anything, but the fact that it's persistent means that you need to investigate further.

Was she ridden during her vetting?
 
She was ridden during her vetting yes.

The vet has advised waiting 2 weeks to see if the pads improve things, but this is worrying incase she has done something more serious. Are they being slack or am I being over cautious?
 
No I don't think they're being slack. However, when a new horse that I had went lame very soon after buying him I insisted on a full work up being done, as I didn't know the horse, only had the history given to me by the seller, and obviously wanted to check that nothing untoward was going on that could have been covered up by Bute at the time of selling.

exactly - although if 5 stage the bloods should show?

but there are other ways of hiding lameness - for example in a BF horse leaving the walls excessively long

on the other hand she may have just developed central sulcus thrush which can be really really painful going downhill and I have yet to come across a vet to notice this. (sadly)
 
My main concern is injury (mainly ligament type) since we are working on the assumption that the lameness is coming from pain in the sole...yet the horse gives no reaction and doesn't mind any kind of squeezing prodding of the sole.

I would be thinking about the structures of the foot. Pedal bone, coffin joint, navicular bone, sesmoid ligament.

Could be anything really.

Let us know how you get on.
