I am so glad there's no burning pain!!! The ROM and push back against the hand seem like a great start. IMHO, if you are doing these things and some touch down pressure (straight on, no bending maybe) that ought to do the trick. Keep those bones safe!
You're right about third day post-op, 4th too. I would expect doing much at this point to be a challenge. Incisions are just sore for a while CRPS or not.
I am sending hugs and prayers for continued healing.
