III. Differential Diagnosis
- See Chest Pain
- 
                          Muscle Strain (overuse syndrome)- Superior: Trapezius Insertion
- Mid: Pectoralis Muscle
- Inferior: Latisimus dorsi insertion
 
- 
                          Costochondritis
                          - Common, costochondral margin pain typically at several sites without swelling or induration
 
- 
                          Tietze Syndrome
                          - Rare, focal costochondral margin pain with localized swelling and inflammation
- Inflammation secondary to localized infection, neoplasm or Rheumatologic Condition
 
- Slipping Rib Syndrome- Hypermobile, tender anterior portions of inferior costal cartilage
- "Hooking maneuver" reproduces pain (and in some cases a click)- Hook fingers under lower ribs and pull anteriorly
 
 
- 
                          Fibromyalgia
                          - Chest Tender Points at second costochondral margin (in addition to 10 total of 18 points positive)
 
- Thoracic Herpes Zoster (Shingles) or Postherpetic Neuralgia- Unilateral, Dermatomal Distribution of clustered Vesicles on a red base
 
- Painful Xiphoid Syndrome- Localized tenderness over the sternoxiphoid joint
 
- 
                          Arthritis
                          - May affect sternoclavicular joint or sternomanubrial joint
 
- 
                          Mastalgia (Breast Pain)- See Mastalgia
 
- Pathologic Destruction of Costal Cartilage (by infection or cancer)- Infection (Bacterial or fungal) or cancerous lesions may cause local destruction of costal cartilage
- Infections are higher risk in post-op state, as well as in intravenous drug use
