There are several other causes of pain on either side of the lower abdomen. It may also happen that the discomfort is experienced on the right side, but the cause of pain is on the left side. Some of the other causes have been listed below:

  • Gas: The entire digestive tract is filled with intestinal gas formed by the food particles which are broken down completely until the time it reaches the colon. More the particles of undigested food left inside more are the gas produced. The stomach thus gives bloated or knotted feel in the stomach as more gas gets formed. The temporary relief of gas is burping and farting. But excessive gas is a sign of digestive disorder such as lactose intolerance and diabetes.
  • Indigestion: Indigestion occurs after eating or drinking and may be a reason for the pain in the upper abdomen, but it may be felt in the lower abdomen. Although, slight indigestion fades away pretty quickly if the symptoms remain it can be concerning.
