A pain in your left side is discomfort anywhere from your lower ribs to your hip. The cause depends on whether it's sharp, dull, constant, or intermittent.
Your left side contains organs like the stomach, spleen, pancreas, and part of your colon. Pain signals travel through nerves to your brain, which interprets them as location and intensity.
The most common causes fall into three categories:
Seek medical attention if the pain lasts more than a few days, worsens, or comes with fever, nausea, or difficulty breathing. Sudden severe pain may indicate a medical emergency.
I once experienced persistent left-side pain that turned out to be gastritis. My doctor prescribed medication and recommended dietary changes, which resolved the issue within a week.
Many people assume left-side pain always relates to heart issues. However, heart-related pain typically radiates to the center or right side of the chest. Left-side pain is more often linked to digestive or muscular problems.
