There are a few things chiropractors treat that a normal person would not think to pursue for treatment by a chiropractor. One of the most popular things in my office is infantile colic. This is a baby that has crankiness, irritability, incessant crying, reflux, and a little sleep. I have seen very good results with light spinal manipulation on babies with colic. Also infantile torticollis. This is where a babies head is cocked off to one side and does not seem to want to straighten out usually from car seats or baby swings. Light manipulation tends to alleviate this problem fairly fast.
Some adult issues the chiropractors see in their office on a daily basis are gastrointestinal reflux disease and irritable bowel syndrome. Which also respond very well to manipulation.
So chiropractors not only treat neuromuscular skeletal disorders but also treat these Visceral disorders such as the above mentioned.
