Sacoiliac joint belt. Pain in the low back and pelvis during pregnancy is considered, by many doctors, to be generated from the pelvic girdle; especially from mechanical torque focused upon the pelvic girdle bony ring and contained joints, the symphysis pubis and two sacroiliac joints. Partial pain relief is sometimes enabled by a sacroiliac belt. Many obstetricians are familiar with and can prescribe. See boa.Com.
