Persistent Physical Symptoms without medical cause

Many children suffer from physical discomfort, while there is no obvious medical problem that causes the discomfort. The general practitioner or pediatrician has examined the child, but without result. Many of these children often already had help from a physiotherapist, again without much result. For these children, the cause of their physical discomforts may be something psychological. Common discomforts are headaches and stomach aches. Other examples are sleeping and/or eating problems, tics, compulsion or bed-wetting. 

These kind of problems are called: Persistent physical symptoms (formerly known as medically unexplained physical symptoms).
