Hi, I dropped my rabbit (or, in more specific terms, he clawed me and jumped way too high) and his reaction was a bit weird…

He lives in a cage + large x-pen area, but he doesn’t like when I sit on the couch outside of the pen because he gets lonely. So I decided to pick him up and let him sit on the couch. He’s done this many times before, but then I realized the door outside the room we were in was open, and that he could be in danger if he got out. So I quickly picked him back up and began to take him back to his pen. But he got upset by this and began flinging and scratching, and he scratched a clear mark across my hand (I had to search the pantry for a big band-aid). I let go and he jumped into the air, thankfully landing in his pen. But as soon as we both had snapped out of our daze he began making a sneezing/coughing noise, sitting up on his hind legs and batting his face with his front paws. This went on for several seconds. I was terrified, trying to figure out what to do. I was so afraid he might choke. But after a few 30 seconds he stopped, and resumed normal behavior. He allows me to give him head rubs and feed him, like usual, but he still coughed a couple times. It’s over now but I’m still worried about it. Are there any injuries I should look out for? He seems to be fine but I’m still extremely worried. He landed on the covered ramp that leads up to his cage, so it was a bit of a diagonal landing, but he seemed to land on his paws and not at all in some weird position.
