I’m 4 weeks post-op now but around the second week I also had pains when I bent over or sat straight up, always at the same spot. I couldn’t sit at a table for too long because of it. My surgeon prescribed me a muscle relaxer, which helped, and it eventually subsided. I tried to make sure I was sitting up every now and then but mainly sat in a recliner so I could lean back a bit and relieve the pressure.
