The next step would be to see a specialist such as a rheumatologist to investigate what disease is causing the calcification.
Diabetes with neuropathy can predispose to trauma, which can predispose to muscle calficiation. Diabetes can also predispose to artery calcification. You need to clarify exactly what is calcified so that the appropriate steps can be taken to diagnose and treat the underlying problem.
It depends on the underlying problem. You should speak to your doctor for clarification regarding where the calcification is and what the next logical step is.
