All normal!
To give you some more confidence regarding how great these procedures are - how understood by the medical profession (even though it is very special for us, the patients) ... my stay was overnight as Medicare requires this, otherwise, the doc said it was OK for out patient, same day surgery with release from hospital same day. They really have a good handle on hips.
We all recover differently, but 99.9% chance your new equipment is working perfectly, and your body is responding normally!
I did supine exercises starting the day after the surgery ... VERY light and easy exercises on the bed consisting of just moving leg left and right slowly for a few reps, then knee raises with foot flat on bed for a few reps ... i elevated and iced in between for an hour. Then, repeated in a couple of hours. Walked around house on crutches in between. Then elevated and iced, again!
Do you have a large silicon ice pack? I got two, one stays frozen that way.
