Rotator Cuff Impingement Pain Characteristics
Rotator cuff impingement typically causes a dull, aching pain that radiates down the upper arm, not a throbbing sensation. 1
Pain Pattern Description
The characteristic pain of rotator cuff impingement and rotator cuff disorders presents as:
- Dull aching pain that radiates down the upper arm 1
- Pain that is present at night, often disrupting sleep 1
- Pain with arm elevation due to soft tissue entrapment in the subacromial space 2
- Pain associated with limitation of motion and weakness 1
Clinical Distinction
The pain quality is important for differential diagnosis:
- Dull ache radiating down the arm = classic rotator cuff pathology 1
- Throbbing pain is NOT the typical presentation and should prompt consideration of alternative diagnoses such as:
- Vascular pathology
- Neurogenic pain
- Inflammatory arthropathy
- Referred pain from cervical spine
Associated Clinical Features
When evaluating the pain pattern, look for these accompanying findings that support rotator cuff impingement 1:
- Deltoid and rotator cuff atrophy on inspection
- Tenderness over the rotator cuff
- Limited passive range of motion
- Weakness specifically on abduction and external rotation
- Pain with overhead activities
Common Pitfall
Do not dismiss arm pain as simple impingement if the quality is throbbing rather than aching. Throbbing suggests a different pathophysiological process requiring alternative diagnostic workup, particularly evaluation for vascular or neurological causes that may require urgent intervention.
