• Sciatica. This is inflammation of the sciatic nerve. The largest nerve in the human body, the sciatic nerve runs from the lower part of the spinal cord, through the buttock and down the back of the leg to the foot. The most common causes of sciatica include compression of the nerve where it exists the spine by a herniated disc, or a rupture of one of the structures that cushions the vertebrae in the spine. Sciatica may be felt as a sharp or burning pain that radiates from the hip. It may also be accompanied by low back pain.
It’s well established that about eight in 10 people in the U.S. will experience back pain at some point in their lives. And while the causes of such pain often vary, say physical therapists and other medical professionals say that increasingly, in a world that accommodates a more sedentary lifestyle, the blame for low-back pain can often be traced to an area a little lower in the kinetic chain: the hips.
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
