This can be brought on by a strain, overuse or muscle weakness, according to BetterMedicine.com.

While lower back tightness can be managed at home, occasionally medical intervention is needed to treat this common condition. Rest your lower back muscles.
Wasp and Scale Insects Help Control Giant Reed. An arundo gall wasp deposits eggs into the main stem of a giant reed. (Image by USDA/ARS) The release of tiny insects to combat the invasive weed giant reed is paying off, according to a recent U.S. Department of Agriculture (USDA) study.
The larva, which is the stage of this insect's life cycle that causes the actual damage to the fruit, is similar to a typical fly larva or maggot. Other worms, especially the larvae of the codling moth, that infest the insides of apples are often confused with the apple maggot.Generally speaking, however caterpillars often feed in the appleâs core while apple maggots feed on the fruit flesh.In infested fruit, the larvae are often difficult to detect due to their pale, cream colour and small body size.The maggot stage has many enemies, including several braconid wasps: Utetes canaliculatus, Diachasmimorpha mellea, and Diachasma alloeum. The adult stage lays its eggs inside the fruit.n infested fruit, the larvae are often difficult to detect due to their pale, cream colour and small body size.
