anybody know what my cat’s paw / leg is doing?

hi so earlier (about 30m before this video) we were playing and she hit her head on my bed post 😭 this is the first time ive seen her do this and idk if i should be concerned. its just different from kneading i guess idk if hitting her head had smth to do with this. I massaged her paw and head but she doesn’t look like shes in pain. thank you for the advice!

((shes 3yo, tabby, around 3kg, active, normal appetite))
