Griping pain in the bowels, especially about the navel; pain, spasmodic in character, generally relieved by pressure; no tenderness of the bowels; frequent vomiting; bowels usually constipated, and frequently flatulent; no fever; pulse generally slower than usual; skin cold.
The term colic is properly applied to a spasmodic muscular contraction of the walls of the intestines, but on account of the difficulty of distinguishing the two conditions, it is often also applied to a neuralgic affection of the intestines known as enteralgia. The disease is usually caused by indiscretions in eating, as of unripe fruit, stale or decaying vegetables or other food, certain kinds of fish, or by taking cold, etc. The disease is often a very painful one, leaving the patient much prostrated, but is never fatal. The application of hot fomentations or dry heat to the abdomen, and the use of large hot enemata, rarely fail to give speedy relief. In cases of chronic enteralgia such as are sometimes met with, nothing is so effective as the use of electricity in the form of a mild faradic current or galvanism.
