How can I tell if she is laying on my sciatic nerve? This morning I woke up to use the bathroom and my legs almost went out on me and caused me to fall. Still when I'm trying to walk I'm limping around like I need a cane and my back is hurts pretty bad on and off. My midwife told me my spine might be out of alignment but I'm not sure if she tell if the baby is laying on the nerve or not.
