Sorry, I know you didn't want to hear that. Well, see what the Drs say about how badly you've torn it, they will give you a better idea-if you haven't been to see them why do you think its the MCL or did I miss something? But there are other things you can do...perhaps groundwork? Cavelettis and lunging?
Just the way it happened and how I it is being, I'm 99% sure it was a ligament issue right after it happened, and afterward, knowing that I've broken bones before but this did not feel like a broken bone, yet it hurt, swelled, and is very instable. I went to get X-rays today to make sure nothing is wrong with the bones involved or that the joint popped out. The x-rays came back good, but they don't really do serious ligament injuries there and only poked and pushed it to see where it hurt precisely. Told me to rest and go get an MRI after a week if it's still causing an issue...
I don't think I should wait a whole week with a possible sprain to get an MRI... Something's seriously wrong when I can't walk right without my knee buckling on its own. I couldn't walk at all today until I wrapped it to go to the clinic, and then they gave me a brace to wear because I complained I was having trouble walking. Apparently starting to cry when they poked it wasn't enough to tell them I was having severe pain? Ugh, can't get decent health care unless you go to specialists nowadays
All the doc said was that I "probably knocked it" or "bruised it" (there's not even any bruising color there, just a little scrape on the front of my knee, not even the side where it's swelling).
What happened exactly is that I was riding bareback on the side of a fence where the posts are out, not the smooth side. Just doing walking exercises near the barn. My mare started losing straightness so I put my leg on to stop her hindquarters swinging out; she leg-yielded toward the fence too much and the post caught my knee. My knee kept going out and behind while she kept going forward, so that my knee went beyond its range of motion and then snapped back after scraping by the post. It wasn't like an impact injury; there's no bruise, no cut, just the top layer of skin rubbed off from where the post made contact.
