Abdominal Pain with Unknown Cause, Male (Child)

Abdominal (stomach) pain is common in children. But children often don't complain of pain because they don't have the words to describe what is wrong and they have trouble pinpointing where it hurts. Often, they just feel bad, or don't want to eat. This can make abdominal pain hard to diagnose in young children. Also, abdominal symptoms are associated with many problems. Most of the time, the cause of abdominal pain in children is not serious and will go away.

Over the next few days, abdominal pain may come and go or be continuous. It may be hard to decide whether a child has pain or is feeling something else. Other symptoms that may occur include nausea and vomiting, constipation, diarrhea, or fever. Sometimes it can be hard to tell whether a child feels nauseous because he or she just feels bad and doesn't associate that feeling with nausea. The child may constantly touch his or her stomach or indicate pain when the stomach is touched.

Abdominal pain may continue even when being treated correctly. Sometimes the cause can become clearer over the next few days and may require other treatment. More tests or medicines may be needed.

Home care

The healthcare provider may prescribe medicine for pain and symptoms of infection. Follow the instructions for giving these medicines to your child.

General care

  • Comfort your child as needed, and give emotional support.

  • Try to find positions that ease your child's discomfort. A small pillow placed on the abdomen may help provide pain relief.

  • Distraction may also help. Some children may be soothed by music or reading.

  • Relaxation techniques and behavioral therapy can be helpful if the pain becomes chronic.

  • Lying down with a warm washcloth on the stomach may help improve symptoms.

  • Have your child sit on the toilet regularly.

  • Don't give medicine for abdominal pain or cramps unless instructed by your healthcare provider.


  • Don't force your child to eat, especially if they are having pain, vomiting, or diarrhea. Think of what would make you feel better or worse, the same probably goes for your child.

  • Water is important to prevent dehydration. Soup, popsicles or oral rehydration solution can help. Give liquids a small amount at a time. Don't let your child guzzle them down.

  • Don't give your child fatty, greasy, spicy, or fried foods

  • Don't give your child dairy products if he has diarrhea. They could make diarrhea worse.

  • Don't give your child high-fiber foods while the pain continues.

  • Don't feed your child large amounts at a time, even if he or she is hungry. Wait a few minutes between bites and offer more if tolerated.

Follow-up care

Follow up with your child's healthcare provider, or as advised. If tests or studies were done, they will be reviewed by your healthcare provider. You will be told about any new findings that may affect your child’s care.

Fever and children

Always use a digital thermometer to check your child’s temperature. Never use a mercury thermometer.

For infants and toddlers, be sure to use a rectal thermometer correctly. A rectal thermometer may accidentally poke a hole in (perforate) the rectum. It may also pass on germs from the stool. Always follow the product maker’s directions for proper use. If you don’t feel comfortable taking a rectal temperature, use another method. When you talk to your child’s healthcare provider, tell him or her which method you used to take your child’s temperature.

Here are guidelines for fever temperature. Ear temperatures aren’t accurate before 6 months of age. Don’t take an oral temperature until your child is at least 4 years old.

Infant under 3 months old:

  • Ask your child’s healthcare provider how you should take the temperature.

  • Rectal or forehead (temporal artery) temperature of 100.4°F (38°C) or higher, or as directed by the provider

  • Armpit temperature of 99°F (37.2°C) or higher, or as directed by the provider

Child age 3 to 36 months:

  • Rectal, forehead (temporal artery), or ear temperature of 102°F (38.9°C) or higher, or as directed by the provider

  • Armpit temperature of 101°F (38.3°C) or higher, or as directed by the provider

Child of any age:

  • Repeated temperature of 104°F (40°C) or higher, or as directed by the provider

  • Fever that lasts more than 24 hours in a child under 2 years old. Or a fever that lasts for 3 days in a child 2 years or older.
