Double up in pain- I'm on my knees

Here are some pictures of my knee today, four days after I injured it. I know, knees are ugly anyway, and I certainly don't have good looking ones under normal circumstances. The interesting thing is that on Saturday, the swelling was on the bottom inside of my right knee (left in photo) but now the swelling is all around, and especially, above the knee.I have been doing some research on my knee and I think it is sprained-well, I hope it is sprained, rather than ligament damage. I use a wrap and can walk on it, sort of, and it doesn't hurt much overall, which surprises me because most of the time my injuries throb day and night. I find it hard to start walking, even my calf muscle hurts, but I can get into a sort of rhythm after a few steps. I do have a strange "tight" sensation around my entire leg, like someone left a blood pressure cuff on my leg, even without the wrap. Anyway, I am trying to be careful not to make it any worse than it is but it is so hard to go feed the horses with the uneven (muddy, icy) ground out by the barn. I can't wait for my leg to get better. A friend was talking about going hiking and I pipped up, "I'll go with you", and then I just groaned and said, "well, maybe, someday..."
