What could cause joint pain in the shoulder when lifting the arm?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Shoulder pain when lifting your arm is often linked to conditions such as subacromial impingement, rotator cuff issues, or general shoulder dysfunction. Subacromial impingement occurs when tendons in the shoulder are pinched during arm movement, causing pain, weakness, and limited range of motion. Treatment options may include rest, physical therapy, anti-inflammatory medication, or in some cases, arthroscopic decompression surgery to relieve pressure and restore mobility.

Because shoulder pain can stem from many possible causes—ranging from minor strain to conditions requiring medical intervention—identifying the likely source early can help you avoid worsening symptoms and choose the right next step. A free, instant, online symptom check can help you clarify what may be behind your pain, understand its severity, and guide you toward the appropriate care.

Explanation

When you experience shoulder pain while lifting your arm, it might be due to issues with how your shoulder functions. This can happen if the shoulder isn't moving as it should, which is important for people who use their shoulders a lot, like assembly workers.

Another possible reason for shoulder pain is subacromial impingement. This is when the space in your shoulder where tendons and muscles move becomes too tight, causing pain. A study showed that a procedure called arthroscopic subacromial decompression can help relieve this pain by creating more space in the shoulder.

To better understand your shoulder pain and get personalized insights about what might be causing your discomfort, you can take a free symptom checker test to help identify potential issues and guide your next steps toward relief.
