It started on & off, some days sound, some lame. I got the chiro to come look at her about 2 weeks after it started. He said she'd dislocated her shoulder, popped it back into place and gave me some stretches and exercises to do. I was to lightly lunge her everyday for a week starting the next day so her tight muscles could stretch out after being out of place. So I did as he said and she seemed to get progressively better. At one point while lunging she only looked lame in the one direction. When the week was up I got on to see how she felt. My coach remarked on how much more relaxed she looked compared to before, but I could still feel/see the head-bobbing so I got off.
I kept up with the stretches and scheduled another chiro appointment.
My farrier came out before the appointment, removed her shoes (at this point I realized I wasn't going to get much riding done this summer) and checked her feet to see if he could see anything. He didn't.
Chiro came out, did some more adjustments to her shoulder, and said to continue stretches/lunging until she was sound. I did as told until one day I went out and she was visibly lame while she was walking. The head-bobbing was quite severe, you'd think she had a nail stuck in her foot!
She was put on stall rest for a week (I didn't want to aggrivate it). At the end of the week she was back to how she was before.
I got the farrier out last week to check if there was an abscess in her foot, he checked both front and found nothing.
Throughout all this she's had no heat in her leg/foot/shoulder and I haven't found any sensitive areas on her leg (that she didn't want me touching).
Sorry for the novel! I just wanted to give a lot of details in case you see something I've missed. I'm really at a loss, my coach is out of ideas and our next step is to get the vet out. The only problem is we don't have any experienced horse vets up here (the closest being 5-6 hours away) so all she'll be able to do is take xrays and send them away to be looked at, and do a wobblers syndrome test (we had a horse in the area diagnosed with it, and now she seems to think every other sick horse has it.)
What's really getting me is that the severity of her lameness keeps fluctuating with no apparant cause. Any ideas would be GREATLY appreciated. I have no idea what to do now.
Here are some videos I took today of her trotting on different surfaces, sorry if they're not great, I didn't get to watch them until we got home.
