Causes. Back pain is a symptom. Common causes of back pain involve disease or injury to the muscles, bones, and/or nerves of the spine. â¢ (a nerve is directly irritated), often due to a herniation (or bulging) of the disc between the lower back bones.
What is the difference between a creek and a crick? Please add where you are from in your answer. One is a body of flowing fresh water smaller than a river, and the other is a pain in the neck. Unless you're from Appalachia, in which case the latter (crick) is an alternative pronunciation of the former (creek). I have yet to find corroborating evidence of this sense/connotation of the word. I'm mostly from California, and out here we call them creeks (rhymes with leeks), regardless of size.
Burrows and Breeding. A crayfish burrow is a cone-shaped mound or chimney composed of mud pellets that mark the entrance to the burrow. Most burrows are located along the shoreline close to the water's edge. These burrows may range from a few inches to greater than 36 inches deep, and will be from 1/4 to 2 inches in diameter.
