A stingray weighing nearly 800lb is thought to be the largest freshwater fish ever caught by rod and line. It was so big that several men on board a small fishing boat had to take it in turns to help on the rod.
The hamstrings, a group of three muscles located in the back of the thigh, can contribute to lower back pain. So keeping the hamstrings properly stretched and limber is a good formula for relief of lower back pain or sciatica pain, which tends to run down one side of a leg. A regular routine of hamstring stretching eases tightness that generates stress on the low back. The hamstrings run from the pelvis down to the knee.
Pain usually spreads across the lower back and may feel like a muscle strain. Spondylolisthesis can cause spasms that stiffen the back and tighten the hamstring muscles, resulting in changes to posture and gait. If the slippage is significant, it may begin to compress the nerves and narrow the spinal canal.
