My incision looked larger than I expected in early days but seemed to shrink as it healed. Probably more swelling than I thought there was. My PT had never dealt with SuperPath patient before and was very surprised by early mobility. He'd researched differences in surgery and treatment protocol and commented about how so many things he did with me broke all the rules he'd ever been taught about dealing with hip replacement patients (not having to follow 90 degree rule, being able to cross the center line, etc.).
While taking the meds before PT can be helpful, note if anything is causing pain other than just general discomfort from moving around - you might want to push those back a bit.
Depending on how you sleep, I found putting a pillow on the bed for my upper leg to rest on better than trying to keep one between my legs. Since my OS allowed (encouraged) crossing the center plane, I was allowed to do it that way. I still didn't try the bed for 10 days because I needed to get rid of the compression cuffs with all the tunes and wires beforehand. It then took me a few days to transition - with longer times in the bed each night.
All in all, sounds like things are progressing well for you. Keep it up!
