Musculoskeletal disorders 

Low back pain is a common presenting complaint especially among the elderly. It may be a mild, transient symptom or chronic and disabling complaint.

It is a common form of arthritis, characterized by degenerative loss of articular cartilage, subchondral bony sclerosis, and cartilage and bone proliferation subsequent osteophyte formation.

Gout is a recurrent acute arthritis of peripheral joints which results from deposition, in and about the joints and tendons, of crystals of monosodium urate from supersaturated hyperuricaemic body fluids. The arthritis may become chronic.

Osteomyelitis is an infection of the bone, and is most common in children under 12 years. Staphylococci are the most frequent responsible organisms.

Tropical pyomyositis is a primary bacterial infection of skeletal muscle characterized by localized abscess formation, muscle necrosis, and systemic inflammatory response. It predominantly affects large muscle groups and occurs most frequently in tropical and subtropical climates.

Unlike secondary muscle infection, it arises without adjacent skin infection, osteomyelitis, or penetrating trauma in many cases.
