This recovery business certainly can be a "what now?" game.
My first thought would be us there a particular exercise or activity that you are doing now that your hip is saying it isn't quite ready for and is causing the uptick in swelling.
I assume you are still icing and backing off of anything that isn't helpful rather than soldiering through it?
I tried very hard to further my recovery and as you say, our expectations can cause teal frustrations as it has its own timeline for healing.
Honestly, if you think there is a serious issue and the OS is willing to see you this week...why not?
I hate to hear that you might feel that still needing meds is a sign of going backwards.
As I got more mobile, I saw that they were not only necessary to be mobile...they were necessary for rest.
These ARE early days still and prime time for these post op blues.
I certainly remember how emotional I was (as does poor hubby

) and it certainly can be overwhelming.
If there are any exercises that PT is requiring other than walking...I would take a week off and see if things improve!
Keep the faith friend...this is a delicate dance at this point between enough and too much.
Let us know what you decide!
Hugs for you
