In this article, we'll look at the parts of the ISS, how it maintains a permanent environment for humans in space, how it's powered, what it's like to live and work on the ISS, and how, exactly, we'll use the ISS.

This is a large nerve that runs from the lower back down the back of each leg. When something injures or puts pressure on the sciatic nerve, it can cause pain in the lower back that spreads to the hip, buttocks, and leg. Up to 90% of people recover from sciatica without surgery.
This, in turn, sensitizes the nerves, causing the muscle/s to contract and spasm. Conditions, such as degenerative disc disease or herniated disc, may cause an acute episode of low back pain. A disc may herniate or bulge and compress a nearby spinal nerve root causing irritation and inflammation.
