When I experienced a searing pain in my right hip while going up the stairs, followed by a deep ache that wouldn’t go away, I immediately recalled my pregnant, unstable pelvis. This was familiar pain. During both pregnancies, I dealt with pretty terrible sciatica. Thanks to the fluid nature of my pregnant bod, the pain frequently switched sides to keep me guessing. In addition to deep aches in my hips most of the time, they would often buckle or give out when I went to stand up.
