Well, injuries as severe as the one you describe can take a lot of time to heal. And the purpose of swelling is to immobilize the affected area, so I wouldn't be trying to flex it much.
If you think the vet is wrong, get a second opinion. I live about an hour and a half from my equine vet. There is a GP ten miles down the road. If I have an issue, I call the GP (she is much better with horses than our last GP). If I don't like what I'm hearing, or if she suggests it, I call the equine guy. There are some situations in which I immediately call the equine vet, but those are rare. The point is, not all vets are created equal. I am in no way trying to malign ANY vet, but if you are not satisfied, you might consider finding another. Keep in mind, though, that some owners often don't like what a vet tells them regarding treatments and/or recovery times. I had a horse go through the trailer floor while it was going down the road, and it took a loooooong time to heal. I really felt bad for him, and I was impatient to see him better, but I followed every single step of the treatment plan because I knew the vet was right.
What do you consider severe swelling? I would go ahead and post the pictures, maybe put a "graphic images" warning in the thread title if you feel that's necessary. But pics will definitely help the rest of us give you advice.
