Constipation: Many people don't realize they're constipated &have enough stool accumulate in the rectum &colon that it can be felt or even seen if the person is thin enough. After eating, the colon tries to empty itself, &when the colon tries to squeeze a large amount of stool it can be painful. Of course the only way to know for sure is to have a medical exam, but you might try an enema and laxatives first.

Ultrasound will not demonstate excessive stool, but a plain x-ray usually will, if the radiologist or ordering doctor are looking for it. Utrasound is generally good for looking at some other causes of lower left abdominal masses, like the ovaries. But other problems in the bowel, like a mass, will not be seen well with ultrasound. If symptoms persist after enema & laxatives, follow up with doctor
