Delayed muscle pain

Had anterior arthroplasty a little more than 4 weeks ago. Was off the walker in 10 days and off the cane in 10 more. Had been walking fine with little pain. Not doing too much. Just walking around the house and down the block and back. A couple of days ago I started getting significant pain in my quad and glute to the point I’m back on the cane. Anyone else experience this delayed muscle pain? If so, did you do anything and how long did it last? Thanks
