Many patients with back pain, leg pain, or weakness of the lower extremity muscles are diagnosed with a herniated disc. When a disc herniation occurs, the cushion that sits between the spinal vertebra is pushed outside its normal position.

A muscle strain is a stretch or tear of muscle fibers. In the leg, muscle strains happen when a muscle is either stretched beyond its limits or forced into extreme contraction. Because the leg has many different muscles, it is vulnerable to several different types of muscle strains. Calf muscle strain (gastrocnemius strain). The calf muscle typically gets strained when the foot suddenly bends upward, stretching the calf muscle beyond its limits. At the time of injury, you may hear or feel a pop inside your calf -- the sound of the muscle tearing or shearing away from the Achilles tendon.
