The appendix is usually situated in the right lower quarter of the abdomen. The usual symptoms of acute appendicitis include pain, often starting round the umbilicus the "tummy-button") and moving across to the child's right side which will be tender to pressure. The pain tends to be constant and it is often worse with movement. The appetite will usually be reduced, and there may be vomiting. The bowels will often have stopped working about 12 hours previously. There will usually be a slight temperature ( 99⁰F to 101⁰ F, 37.2⁰C to 37.8⁰C) and the tongue may be slightly coated, rather than the normal healthy pink colour.
