Tickle:
Osteomyelitis is infection of the bone itself and may effect the bone marrow eventually.
Osteomyelitis: eMedicine Emergency Medicine Quote:
The infection associated with osteomyelitis may be localized or it may spread through the periosteum, cortex, marrow, and cancellous tissue. The bacterial pathogen varies on the basis of the patient's age and the mechanism of infection |
A bone marrow infection cannot be definitively defined on xray. a bone marrow biopsy is needed.
In addition, on xrays bone is light or white because of calcium content. You cannot "see" bone marrow because it is dark. Therefore, you cannot tell bone marrow disease by plain xrays.

Other potential cause
osteoporosis - though no pain without fracture
vitamin d deficiency

Leprosy is a disease of the skin and nerves. Bone is only effected due to the neuropathy caused by the m. leprae.
Leprosy: eMedicine Infectious Diseases Quote:
Leprosy is a chronic infection caused by the acid-fast, rod-shaped bacillus Mycobacterium leprae. Leprosy can be considered 2 connected diseases that primarily affect superficial tissues, especially the skin and peripheral nerves.....
Although both lepromatous leprosy and tuberculoid leprosy involve the skin and peripheral nerves, tuberculoid leprosy has more severe manifestations. Nerve involvement results in loss of sensory and motor function, which may lead to frequent trauma and amputation |
