Hi there, I keep reading all these wonderful answers and hope someone clarify things for me. I found out I had scoliosis of a 24 degree curvature when I was 18. No, never had surgery and never considered it. I'm now 28 years old (5'8, 130 lbs) and 21 weeks pregnant with excrutiating pains in my lower back. It's been steadily getting worse over the past 2 months to the point where almost every step I take will take my breath away (bc of the pain) and I even almost fell twice just walking. It felt as though I just didn't have a leg. I went to an orthopaedist who informed me that I have two curvatures at the lower back, first to the right then to the left. I can't have an MRI (being pregnant) but after a few simple tests he was explaining that with the uterus growing it's causing more pain on my back and (here's where I'm confused) it's the muscles or nerves that are tearing away causing the pain? He also explained something about the nerves or muscles? that are hitting my sciatic nerve which is causing the numbness in my leg and that's why it just doesn't work sometimes and I start to fall. Can anyone clarify this for me?
