Then I'll say a few more words myself

This situation is usually called pole, which is a common phenomenon in long-distance running. If this happens. Don't stop running at once, slow down a little, and then press your hand to the painful place. Hold it with two fingers, and then adjust your breathing. Usually it will slow down after more than ten seconds.

Another key point is to make full preparations for exercise and strengthen exercise at ordinary times.

It may be caused by exercise stimulating muscles or internal organs.

Could be dyskinesia:

Congestion of liver and spleen-due to insufficient preparation activities

Respiratory muscle spasm-respiratory disharmony during exercise

Gastrointestinal spasm-exercise too early after meals, eat too much before exercise, exercise on an empty stomach (stimulated by gastric acid or cold air), and eat foods that are easy to produce gas or difficult to digest (such as beans, leeks, beef, etc.). ) before exercise.

If this happens, reduce the intensity of training, adjust breathing, or massage the painful part and bend down for a while.

Exercise should be scientific and step by step. If this is not the case, and the pain has not disappeared or eased, you need to see a doctor for diagnosis.
