By the way
Appendicitis can strike quite suddenly, causing pain in the abdomen. The patient often begins to feel this pain near the navel, from where it moves to the lower right side of the abdomen and intensifies into a constant ache.
Diagnosis is tricky because the symptoms vary and may develop over 4 to 48 hours but call a doctor if the pain worsens or continues after four hours, or keeps the patient awake. Watch also for any of these symptoms: nausea or vomiting, foul breath, loss of appetite, pain while walking, burning sensation while urinating or a high temperature.
While waiting for a doctor or ambulance, keep the patient still with a hot-water bottle wrapped in a towel on the abdomen. Give no food, drinks, laxatives, painkillers or other drugs. Rinse the patient's mouth with sips of water.
In another form of appendicitis, called chronic, symptoms can come and go for months before an operation can be recommended.
