I definitely get SI and hip pain! It is constant but varies day to day. I bought a hip pillow that sits between my legs just above my knees so I can take some pressure off the area at night and it helps some. I take Celebrex and Enbrel also (on week 10 myself!) I try to rest when I hurt more than usual but continuing to move (low impact like walking and stretching) actually improves the pain. It is counter intuitive at first, but keeping moving is critical if it doesn’t cause too much discomfort (even just a very short walk to avoid the same position for too many hours - if you’re like me working at a desk all day). I also bought a larger gel ice pack to use on the area since it is a larger area to try to ice. That helps a lot!
