When Your Skeleton Starts Playing Transformer
When your OB-GYN gives you the heads up that a hormone called relaxin will spike in your bloodstream to prepare you for delivery, you might think it sounds like just what you need. Unfortunately, it isn’t there to help you melt into the sofa with your favorite blanket and a Netflix binge.

Relaxin surges around your body, acting as a loudspeaker that announces to your joints and ligaments that it’s time to start loosening up because there’s a baby on the way. Some joints and ligaments comply with this demand even though they aren’t involved in delivery, giving us confusingly ridiculous pains. Is skeleton shifting a valid excuse to miss work? Because it should be.
