Swimming is one of the best low-impact exercises for staying active, but spending long hours in the pool or enjoying water sports can sometimes leave you with an aching shoulder. If you've noticed pain during or after swimming, don't ignore it—your body may be signaling an overuse injury.



Whether you're swimming laps, paddleboarding, kayaking, or simply enjoying summer on the water, understanding the cause of shoulder pain can help you recover faster and prevent more serious problems.

Why Does Swimming Cause Shoulder Pain?

Your shoulder is one of the most mobile joints in the body, making it especially vulnerable to repetitive motion injuries.

Activities that commonly lead to shoulder pain include:

• Lap swimming
• Paddleboarding
• Kayaking
• Canoeing
• Surfing
• Water skiing

Repeating the same overhead movements over and over can irritate muscles, tendons, and joints.

Common Causes of Shoulder Pain

Several conditions may be responsible for pain after swimming, including:

• Rotator cuff strain
• Shoulder impingement
• Tendinitis
• Bursitis
• Muscle strain
• Joint inflammation

At first, the discomfort may only appear after activity, but without treatment, it can become more frequent and severe.

Signs You Shouldn't Ignore

It's time to have your shoulder evaluated if you experience:

• Pain that lasts several days
• Pain when lifting your arm overhead
• Weakness in the shoulder
• Clicking or catching sensations
• Limited range of motion
• Pain that interrupts sleep

Early treatment often prevents a minor injury from becoming a chronic condition.

How to Protect Your Shoulders

To reduce your risk of injury:

• Warm up before swimming or paddling.
• Stretch your shoulders after activity.
• Gradually increase your workout intensity.
• Take breaks during long sessions.
• Strengthen your shoulder and upper back muscles.
• Stop if you feel sharp or worsening pain.

Listening to your body is key to avoiding overuse injuries.
