PMD and JHS. A twenties female with unexplained "butt" pain (sciatica) ; "painful cycles" (premenstral disorder, pmd) might have loose pelvic girdle joints, which become even more loose as the hormone relaxin is secreted during each menses. These symptoms are magnified in women with joint hypermobility syndrome (jhs), who have similar intensities of painful sciatica ; pelvic-back pain during pregnancy.
