What kind of stomach pain do you have?
Almost everyone gets belly pain now and then, and most of the time it is not serious. How the pain feels gives clues to the cause:
- All over the belly: more typical of a stomach virus, indigestion or gas.
- In one spot: may come from a specific organ, such as the appendix or the gallbladder.
- Cramp-like: usually not serious and often followed by diarrhea.
- Colicky, coming in waves: often starts and ends suddenly and is severe, as with kidney stones or gallstones.
How we help with stomach pain by video
You see Dr. Diana Nieves Castro, a Puerto Rico–licensed general practice physician with several years of emergency-department experience, in English or Spanish. That experience matters here: she knows which pain can be handled at home and which needs an ER now.
We evaluate, diagnose and treat. The doctor asks where it hurts, how it started, how long it lasts, what you ate, whether you have fever, vomiting or diarrhea, and which medicines you take. If needed, we give you a lab order for blood, urine or stool tests at a lab near you. If appropriate, the doctor prescribes and we send your prescription to your pharmacy. If the pain needs an in-person exam or imaging, we tell you and refer you. It is virtual urgent care for what is not an emergency.

Common causes of stomach pain
The table on this page sums up the most common causes. The less serious ones are gas and indigestion, a stomach bug or food poisoning, constipation, irritable bowel syndrome, gastritis and reflux. More serious causes include appendicitis, a bowel blockage, pancreatitis, kidney stones and a pregnancy outside the womb (ectopic pregnancy).
More clues: if the pain comes with feeling sick to your stomach, read nausea. If you are traveling and have cramps with diarrhea, it may be traveler’s diarrhea. If it started 3 to 6 hours after eating reef fish such as barracuda or grouper, think of ciguatera. And cramping in the lower belly during your period is usually period cramps.
Stomach pain in Puerto Rico: watch for dengue
Dengue is present in Puerto Rico. If you have had a fever in the last few days and now your belly hurts or is tender to the touch, that is a warning sign of severe dengue, especially if you vomit 3 or more times in 24 hours or bleed from the nose or gums. It often appears as the fever goes down. Go to the ER right away and read the dengue warning signs.
Stomach pain in children
In children, belly pain usually comes from a virus, constipation or gas. If there is diarrhea or vomiting, see diarrhea and vomiting in children. The doctor evaluates your child by video with you on camera; patients under 21 need a parent or legal guardian on camera with ID.
For safety, go to the ER if your child has severe pain in the lower right belly, green or bloody vomit, cannot keep fluids down, is peeing very little, is very listless or hard to wake, or is a boy with sudden pain or swelling in a testicle.
Pain in your side? It may be a kidney stone
Severe pain that starts and stops suddenly in the side of the back or the belly, and moves down toward the groin, may be a kidney stone. It can come with blood in the urine, nausea and vomiting. Stones are confirmed with imaging done in person: if the doctor suspects one, she refers you to where to go. Go to the ER if the pain is not controlled, or if it comes with fever and chills or vomiting. See also blood in urine.
Home care, and when to get checked
For mild pain without warning signs:
- Sip water or other clear fluids.
- Avoid solid food for the first few hours.
- If you vomited, wait about 6 hours, then eat small amounts of mild food such as rice or applesauce.
- If the pain comes after meals, an antacid may help.
- Do not take pain medicine without checking first.
- Get checked if the pain lasts more than a week, does not improve within 24 to 48 hours or gets worse, or comes with fever, diarrhea that does not go away, or unexplained weight loss.
