Shoulder pain that won’t improve with exercise?
The problem might be deeper than rotator cuff muscles
Suprascapular nerve entrapment is an often-missed cause of shoulder pain and weakness.
The suprascapular nerve supplies key rotator cuff muscles that lift and rotate your arm. When this nerve becomes irritated or compressed—often from repetitive overhead activity—it can cause pain, strength loss, and poor shoulder control.
Common signs include:
• Deep or posterior shoulder pain
• Weakness with lifting or rotation
• Symptoms that don’t respond to typical “rotator cuff” treatment
• In some cases, visible muscle loss
This condition is frequently seen in swimmers, throwers, tennis players, and weightlifters.
The good news:
When identified early, physical therapy can reduce stress on the nerve, restore healthy shoulder mechanics, and prevent long-term weakness or muscle wasting.
