Imagine getting ready, and tying your running shoes, then only to find an unexpected pain in your shoulder.
Shoulder pain when running can disturb the rhythm and fun of the runner. Reasons such as poor posture, muscle tension, and wrong arm swing are factors behind the pain.
Knowing the causes is important for finding natural relief for shoulder pain and having a pain-free run.
Understanding Shoulder Pain in Runners
It is essential to understand the role of shoulders in running and know the causes and prevention methods of the pain.
The Role of Shoulders in Running
Your shoulders play an important role in maintaining balance and posture while running. You need to position your shoulder properly for overall running mechanics, ensuring a structured arm swing.
You need to keep your shoulder relaxed and stable for better breathing and less strain on the neck and upper back muscles.
Common Causes of Shoulder Pain
Cause | Symptoms | Preventive Measures |
Poor Posture | Shoulder strain and neck pain | You have to maintain an upright posture with relaxed shoulders |
Muscle Tension | Shoulder discomfort and upper back tightness | Practice relaxation techniques and make sure your shoulders are relaxed when you run |
Improper Arm Swing | Shoulder muscle stress and inefficient movement | Keep your arms at a 90-degree angle. Swing them forward and backward without crossing your body’s midline |

Incorrect vs Correct Running Posture

If you run properly, and do shoulder strengthening exercises, you can reduce the risk of shoulder pain. You can do these exercises, such as shoulder presses, lateral raises, and rotator cuff.
Identifying Specific Shoulder Pain Issues
Left Shoulder Pain While Running
You can experience left shoulder pain while running and while doing cardiovascular activities. This pain can mean a lot, depending on factors such as the specific location and type of discomfort.
- Muscle Strain: Over or improper use of the shoulder can lead to muscle strain and then pain.
- Rotator Cuff Injuries: Tears or inflammation in the rotator cuff muscles can cause shoulder pain. Physical activity makes the pain worse.
- Referred Pain: Sometimes pain from the neck or upper back can come into the shoulder.
- Cardiac Issues: Sometimes left shoulder pain can be a sign of cardiac issues. Moreover, if it comes along with chest pain or shortness of breath, then definitely, there’s a cardiac problem.
Right Shoulder Pain During Cardio
Here’s your answer to, ‘Why does my right shoulder hurt when I run?’.
Right shoulder pain during cardiovascular activities may happen because of:
- Muscle Imbalances: If you overwork certain muscles and neglect others, this can lead to imbalance and cause pain during cardio.
- Improper Form: Wrong posture while doing cardio can strain your shoulder muscles.
- Gallbladder Issues: If you have gallstones, then during physical work, your right shoulder might hurt.
- Rotator Cuff Injuries: Your right shoulder can also suffer from rotator cuff injuries if you overuse or use improper form.
Front Shoulder Pain When Running
Front shoulder pain when running can happen due to:
- Biceps Tendonitis: Repetitive motions create inflammation of the biceps tendon. And this can cause pain in the front side of your shoulder.
- Shoulder Impingement: This happens if you compress tendons during movement, and pain occurs.
- Poor Posture: Anterior shoulder pain happens from muscle imbalances due to slouching or hunching.
Effective Strategies to Prevent and Alleviate Shoulder Pain

Breathing Techniques to Reduce Shoulder Tension
Proper breathing can reduce shoulder tension:
