Infective myositis, specifically coded as M60.012 in the ICD-10 classification, refers to an inflammatory condition of the muscle tissue in the left shoulder caused by an infectious agent. The management of this condition typically involves a combination of pharmacological and non-pharmacological approaches tailored to the underlying cause of the infection and the severity of the symptoms.

Standard Treatment Approaches

1. Antibiotic Therapy

The primary treatment for infective myositis is the use of antibiotics, especially if the infection is bacterial. The choice of antibiotic depends on the suspected or confirmed pathogen. Commonly used antibiotics may include:

• Penicillins (e.g., amoxicillin)
• Cephalosporins (e.g., cefazolin)
• Clindamycin for anaerobic infections
• Vancomycin for resistant strains like MRSA (Methicillin-resistant Staphylococcus aureus)

In cases where the infection is viral or fungal, appropriate antiviral or antifungal medications will be prescribed instead[1][2].

2. Supportive Care

Supportive care is crucial in managing symptoms and promoting recovery. This may include:

• Rest: Limiting movement of the affected shoulder to reduce pain and prevent further injury.
• Ice Therapy: Applying ice packs to the shoulder can help reduce inflammation and alleviate pain.
