I had one much like that, the swelling never went away. She did fine unless she took a trailer ride or got mounted for breeding, then she limped for several days after. After breeding the limp was VERY bad for a day or two and I worried she wasn't moving enough to graze and water. I couldn't let her suffer like that, although I did get two calves from her. I should mention she was swollen like that when I bought her as a yearling, but the vet said it wouldn't affect her and I guess it didn't. Most of the time all I noticed was the swelling but when she was hurting it was clear the pain was bad. If you are planning to breed her, you might keep that in mind unless you AI.
