1 Sports like gymnastics and rowing that require athletes to bend backward a lot can also cause back injuries.  Discs that have degenerated (broken down) over time and degenerative arthritis of the spine bones (vertebrae) are the most common causes of chronic low back pain.
Activities such as bending the knee, kicking or running can worsen the pain. The calf muscle, or gastrocnemius, aids in propelling you forward while walking or running. A strain at the upper end of the gastrocnemius causes pain in the back of the knee that worsens with knee bending or rising to your tiptoes.
