Can muscle strain or poor posture cause pain under the left ribs?

Pain under the left ribs can indeed be caused by muscle strain or poor posture. According to the medical literature, musculoskeletal problems of the chest wall, such as those experienced by athletes, can lead to pain in this area. Poor posture can place additional stress on the muscles around the ribs, potentially leading to discomfort or pain.

1. Muscle Strain: A side strain, which involves the tearing of the internal oblique muscles, can cause significant pain under the ribs. This type of injury is often seen in athletes and can result from sudden movements or overuse.

2. Poor Posture: Maintaining poor posture over time can lead to musculoskeletal problems, as it places uneven stress on the muscles and can lead to pain in the chest wall, including under the ribs.

If you experience persistent pain under the left ribs, it may be helpful to review your posture and consider whether recent physical activities could have strained your muscles.
