Hi, it is acceptable that you hurt more after physio, especially if you were sensitive.
You should tell your physio that you had/have more pain. He is the one who saw you, so he can explain you best the causes for your pains. Of course, you can always ask for a second opinion...
I don't believe it is possible to have cracked any bone with his hands, if the box couldn't! That is not a thing to worry about.
It seems you just need to put some ice 3times a day for 10 min, and rest for 5days. Let me know how you recover.
