@stretchchat0: Pain at your SIJ? Try this movement! If you constantly feel a dull ache right above your tailbone or deep in your lower back—especially after sitting for a long time—your Sacroiliac Joint (SIJ) might be locked up or irritated! Don't just force-crack your back. #SIJointPain #LowerBackPain #MobilityRoutine #StretchChat #BackRelief
