Posterior pain

Ok guys I'm on day 4 with surgery day being zero after posterior rthr. I'm still in so much pain. Running a 100.0 fever for days. When did the pain start to ease up for y'all out there with posterior total hip replacements? I'm doing my light PT every day and walking loops around the house for 5 minutes a few times a day. But man this crap hurts. Ok I'll shut up now.
