Back labor is a type of labor that women can experience. This type of labor is characterized by intense lower back pain during contractions, often with pain lingering between each contraction. Where normally there would be a clear break in between a contraction to allow for rest, many women who experience back labor do not get that break.
For women who experience back labor, their contractions are felt mostly in their backs instead of in their front. This can make it difficult for some women to walk around and move freely while in labor. For some women, being submerged in water only helps to alleviate a small portion of the discomfort.
Women who experience back labor often have longer labors and they may require more pushing if baby presents in a posterior manner. If baby is posterior during labor, however, he will most likely rotate before delivery.
