Impingement syndrome occurs when the tendons over the shoulder become inflamed from rubbing in the subacromial space. This irritation thickens these tendons, causing more pain.

Symptoms

• Pain located in the front and side of the shoulder during forceful overhead motions
• Pain at the back and front of the joint during abduction or ER (external rotation)

Treatment

• Rest and ice
• Slow return to sport
• Anti-inflammatory medication when necessary
• Injection of steroids when necessary
