What is flank pain? Causes of lateral pain or flank pain

When performing a run or some type of training, we often feel pain in the lateral region of our body, just below the ribs. This pain is popularly called “flank pain” or even “lateral pain”. However, the correct term is transient abdominal pain associated with exercise.

This pain always starts in the region below the rib when performing an exercise. It's so intense that it usually forces us to interrupt the physical activity until the discomfort passes.

There are several theories to explain why this pain happens. We usually associate pain with breathing, since, by breathing slowly, the discomfort disappears. However, this is not the only reason that leads to this pain. Here are some of the main theories that exist to explain pain in the flanks:

Reduced blood flow to the diaphragm, a muscle responsible for breathing. This theory, despite being widespread, is one of the least accepted today.

Warming up performed improperly and excessive exercise.

Diaphragm compression due to excess food in the stomach.

Diaphragm discomfort due to movement of internal organs.

Incorrect breathing.

Fatigue triggered by friction between internal organs.

Problems of posture.

Note that many theories are proposed, but none proves conclusive. Despite this, you can resort to some measures to avoid the famous pain. Here are some tips:

Do breathing exercises. In addition to helping with physical activity, it will improve your quality of life even with regard to speech.

Never overdo the exercise. Knowing your limits is essential to not harm the body.

Eat at least an hour before training.

When carrying out activities in gyms, for example, always follow the recommendations of a Physical Education professional.
