Is my toe broken?

So me and my friends were at the gym and I fell off the treadmill while I was running and talking to my friend lol. I was fine, I had some scratches on my knee and arm but it wasn't anything serious. I soon realized that I had a lot of pain in my big toe. I don't know how I injured it on the treadmill, but it hurts a LOT (even more when I try to move it.) It's been a couple of hours and it still hurts and I can't walk on it. I don't know if it's broken but when I move my toe around it moves weird and pops. The pain is intense but it has subsided after a couple of hours and it hurts a little without touch, but it's bad when I try to walk on it/move it. There is a bruise forming and it is swollen. Could it be a break/sprain/fracture? Should I go see a doctor?
