I was painting my living room and hallway walls and moving lots of furniture around and then did some pc repairs- yup over did it.. and my sacroiliac is hurting too.
prob from up and down the step stool while doing the ceiling edges & trim paint.
but got in for some sessions of PT at dr office and then hope to do maintenance sessions there on my own using the equipment.
they have stair steppers & a treadmill too
