Got steroid shots to help with baby’s lung development and now my SPD pains are gone

Does this make sense? Has anyone experienced this? I had very severe tailbone pain that made even rolling over in bed feel like I was going to split in half. I couldn’t walk very far or sit too long. I had two steroid shots in my hips earlier this week and the pain has been completely gone for two days.

To add, I had this tailbone pain after my first was born and before I became pregnant again. This baby definitely made it more painful though. It has been immensely painful and contributed to my severe depression and so far it’s randomly gone all together since the day after the first shot.
