OK, so Linda now knows what is wrong with her back. It's not actually her back that's broke. She has a tendon tear in her gluteus maximus muscle near the piriformis. In dummy terms, her butt is broke. The tear is at the end of the muscle where the tendon attaches to the bone. There are all sorts of nerves woven in and around the muscle. Since it is inflamed and irritated, it is causing the entire area to cramp up and spasm, including her lower back. Along with physical therapy and ultra sound, she needs to rest in order for it to heal. If she does not rest, it could turn chronic. At least we know why she has been in so much pain.
