Possibly: An early twenties female with low back pain worse in bed might have pelvic girdle instability due to sacroiliac joint ligament laxity; worsened by mattress ground force torque of loose pelvic girdle; usually better lying on good side with pillow vs. Knees & soft mattress best. If vertebral disorder & disk problem then moderately firm mattress is better & discomfort usually worsens when upright.
