My 4 yr old son has been crying & yelling saying his tummy hurts for a few hours i think he may be constipated but he won't even stand without crying?

Stomach Pain: Hello! Constipation can cause significant stomach pain to the point where a child may cry. There are other conditions that also cause significant stomach pain that are urgent and require prompt evaluation. I recommend your son see a doctor today for examination of his stomach to determine exact cause of the stomach pain. For future consultations, my link is healthtap.com/vanessanealmd PNYTKV.

Abdominal pain : You need to take him to his pediatrician ASAP or go to ER, particularly if the pain is persistent, located in Rt lower abdomen, associated with fever or vomiting. I hope he gets better soon.
