I am 28 weeks pregnant. Just over 10 days ago I tore the annular part of a disc in my lumbar spine. I ve been exercising up to this point, but do have a previous back injury in the same area, in which I compressed a lumbar disc, and have suffered from SIJ dysfunction ever since. I also have scoliosis. I would like to give birth naturally- will this damage my back even more? Or is it wiser to have a C-section?
