The term sciatica can be a misleading term when associated with causes of lower back pain. It is important to clarify that sciatica is not just a condition the term can also be used to diagnose many different signs of a condition or illness. Another misconception is that sciatica is always caused by a problem with the sciatic nerves. However, there could be other reasons for example, compression to the base of the nerve or a ruptured vertebrate or disc.
