What's wrong with the pain on the left side of my abdomen while running

The pain on the left side of the abdomen during running may be caused by exercise-induced abdominal pain, gastrointestinal spasms, muscle strains, intercostal neuralgia, urinary system problems, etc. It can be relieved by adjusting breathing rhythm, supplementing electrolytes, hot compress massage, and other methods.

1. Exercise induced abdominal pain

Diaphragmatic spasms during intense exercise are the most common cause, often seen in novice runners or people who exercise immediately after a meal. The diaphragm experiences hypoxic pain due to respiratory disorders, manifested as sharp stabbing pain in the left costal area. It is recommended to immediately slow down and switch to brisk walking, with hands on hips for abdominal breathing training. Slowly inhale through the nose until the abdomen is raised, and then pout and exhale slowly.

2. Gastrointestinal spasm

Running on an empty stomach may cause gastric acid to irritate the mucosa, while full exercise can lead to mesenteric tension. Left side pain is often accompanied by excessive bowel sounds, which are related to the position of the splenic flexure in the colon. One hour before exercise, it is recommended to consume bananas or whole wheat bread in moderation and avoid high fiber foods. During an attack, press the Zhongwan acupoint and massage clockwise.

3. Abdominal muscle strain

Sudden acceleration or turning when core strength is insufficient can easily cause damage to the external oblique muscle, with clear pain points and aggravated compression. Commonly seen after variable speed running or mountain training, it may be accompanied by local swelling. During the acute phase, exercise should be stopped and ice should be applied. After 48 hours, use blood activating and stasis removing ointment for gentle massage. During the recovery phase, flat support training can be performed.

4. Intercostal neuralgia

Shallow breathing can cause sustained tension in the intercostal muscles, which may lead to costochondritis or nerve compression. The pain is distributed in a band like pattern and worsens with breathing, which is related to running posture with a hunchback and chest. It is recommended to keep the trunk upright while running, and do chest expansion and stretching after exercise. If the pain persists, consider using nonsteroidal anti-inflammatory drug patches.

5. Urinary system problems

Symptoms of left kidney stones or ureteral spasms worsen during bumpy exercise, and pain often radiates to the perineum. May be accompanied by frequent urination and urgency, which is related to dehydration during exercise. It is necessary to supplement electrolyte containing drinks in a timely manner. If hematuria or persistent colic occurs, medical examination should be sought, and attention should be paid to controlling the intake of high oxalate foods in daily life.

To prevent abdominal pain during running, it is important to warm up thoroughly for 10-15 minutes before exercise and use dynamic stretching to activate the core muscle group. Maintain a uniform breathing rhythm during running, and it is recommended to use the three-step one exhale three-step one inhale mode. Timely supplement electrolyte water containing sodium and potassium after exercise, and avoid eating raw and cold foods immediately. 1-2 days off per week should be arranged, combined with low impact exercises such as swimming or yoga for cross training. If pain recurs or accompanied by fever and vomiting, abdominal ultrasound and urine routine examination should be performed to rule out organic diseases.
