Highs and lows

On 31st March I had a great ride on Red through the woods. We had a couple of canters and he even offered trot going up hill! Before his diagnosis when ever we went for a canter he would do a few strides and then want to drop back into trot, but on that day he was so much more forward. The next day I took him in the school and he didn't feel quite right on his near fore so I cut the session short. I decided to take him out for a wander on the downs to see how he was the day after. About 3 times on the way out he took a sore step, as if he had stepped on a sharp stone, so I got off and lead him back home. In the round pen he was sound on the left rein but intermittently lame on the off fore on the right rein. Abscess?? I decided to turn him out and was fully expecting him to show an abscess within the next few days. Nothing. I washed his feet off to have a closer look at them and discovered what looked like bad bruising on his soles. The shape of it looks like it could be his pedal bone...could his soles be that thin??? I began to think that we had over done it on the ride days before and he needed time to let the bruising go down. 3 weeks later he seemed sound again so I took him in the school to see how he felt, I just did 10 mins and he was sound in trot. The next day when I flicked a small stone out of his foot a load of puss came out too!!! I was right, it was an abscess all along!!!
