Honestly, worrying too much about stuff like this only leads to a vicious circle- you worry, put something off, worry more… Don’t fret over it. If you have a nice ride inside, then go for a wander outside. If he’s anything like mine, he’ll be picking up on your general worry/tenseness and feeding off that.
Another thought- what’s he being fed? If he’s full of energy because he’s being fed the same as he was when before you got hurt, then that’ll make him jumpy.
