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.
When low back pain begins, the patient may put a stretching program into action by stretching the hamstring muscles in the back of their thighs. This stretch can be beneficial for cases of uncomplicated, mechanical low back pain. However, if the patient has pain radiating down the back of their legs from an inflamed nerve (radiculopathy), then the stretching may not be a wise idea.
