Inline citation guide — Main article mapping

Intro / Prevalence: Back pain affects 50-80% of pregnancies [1,12] with 68.5% point prevalence in current pregnancy [2]
Hormonal Mechanism: 10-fold relaxin rise softens ligaments [3] via RXFP1 signaling in symphysis [4]
Persistence: 8-10% SI joint dysfunction persists 1-2y postpartum [5]
Period Pain: Prostaglandin overproduction causes referred LBP [6]; PGF2α elevated in menstrual fluid [7]
Inflammation 2025: Leukotrienes & EETs beyond PGs [8]
Guidelines: ACOG PB 233 [9] & NICE NG126 [10] for triage & management
Management: Physio meta-analysis for dysmenorrhea LBP [11]; Diff framework [13,14]
Diff Dx: Hormonal sensitivity across cycle vs pregnancy [13,14]
