It bounces back quickly. It looks like fluid. I can’t see it come out the other side of the leg. It’s not a tumor. It doesn’t feel like a lump that is attached to anything, and it is not in the skin. It isn’t hot. The other leg looks a little filled in the same area, but no visible bump. Her hocks look like they might have a little puffiness as well. It looks a little flatter, I think. She hasn’t done anything but eat for almost a week.
This horse NEVER lays down or rolls. I have seen her do it twice. Once when she had sore feet. The other was when she had 106 degree fever with tick fever. I have always wondered if it puts more wear and tear on her legs.
Attached is a new picture of the bump, and then two pictures of her hocks. When I look at my 6 year old, everything is tight. She has big indentations on the side of her hocks. The old mare’s hocks are filled in the same area.
