Differential Diagnoses

Differential Diagnosis I : Tendonitis

Inflammation of the tendons that typically affects the shoulder (rotator cuff), hip, heel, and hamstring. Tendonitis can be cause by overuse or traumatic injury to the joints, etc.  Tendonitis can lead to other diseases of the joints such as bursitis (Sommers, 2019). The patient commonly experiences pain from work related stress therefore, it is unlikely that he is developing tendonitis.

Differential Diagnosis II : Septic Arthritis

Disease caused by the colonization of bacteria in the joint space. The incidence of septic arthritis is seen higher in there elderly and in adolescents. Common pathogens include Staphylococcus aureus and Neisseria gonorrhoea (Golding, Baldor, & Domino, 2019). A synovial fluid analysis is the primary diagnostic measure that determines polymorphonuclear leukocytes and the pathogen  causing the disease.

Differential Diagnosis III : Pseudogout

Characterized by the presence of calcium pyrophosphate dihydrate (CPPD) crystal deposition between the joints. Diagnosis requires the presence of CPPD in the synovial fluid. Monosodium urate crystal deposition is associated with gout (Golding, Baldor, & Domino, 2019).
