It hurts from chest to pelvis on left side?

Need more specifics: Discomfort covering a wide body area such as "It hurts from chest to pelvis" is not possible to diagnose without more information. I suggest speaking with a physician at Health Tap or your own physician.

Many possibilities: Are there any other symptoms to suggest a source? Increase gas / bloating in the abdomen? Constipation or diarrhea? Fever, cough, shortness of breath? It could be anything from pneumonia to colitis to a viral infection. You should see a doctor to be evaluated.
