I am not medically trained, but I suspect that you will have more screening before you are diagnosed. Your physician may opt for a bone marrow biopsy and scans to check for bony lesions.

One thing to keep in mind, is that this pesky M protein presents differently in almost every person I speak to on Connect. We are all so different, largely due to coexisting medical conditions, age and physical stamina.
What type of physician have you been working with and what does he or she say?
