Pain on the left side of the body: What could it mean and when should you pay attention to it?

Why does  pain occur on the left side?
Pain on the left side can be due to various everyday factors or problems with organs and muscles in this region. Important structures such as the stomach, spleen, pancreas, left kidney, parts of the large intestine, heart, and left lung are located on the left side. Examinations and clinical observations suggest that the location and nature of the  pain often provide clues as to what is happening.

However, this doesn’t mean you should jump to conclusions. Many cases turn out to be mild and can be managed with simple lifestyle adjustments.
