Bone pain is the most common early symptom of myeloma. Most patients feel pain in their back or ribs, but it can occur in any bone. The pain is usually constant and made worse by movement… Slightly increased activity, such as coughing and minor falls or injuries, can also result in broken bones and cause pain.

Patients may experience repeated infections because the antibodies they need tofight invading viruses, bacteria or other disease agents are not made efficientlyand in adequate numbers. A urinary tract, bronchial, lung, skin or other type ofinfection may be the first sign of the disease. In addition, recurrent infections maycomplicate the course of the disease.
