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.
It is easier for water to move through bigger spaces. Gravel has very large spaces so water moves through it very fast. On the other hand, the spaces in clay are so small that almost no water moves through. Some layers of rock are so solid that they don't let water move through; this is called an impermeable layer. Others are very crumbly or have lots of big cracks. If the cracks are connected to each other, then water can move thorough the rock. Permeability decreases moving left to right due to soil and rock type.
