Hello Pat
If your doctor suspects myeloma he/she should have ordered the appropriate bloodtests that would help diagnosis. When I started showing my symptoms my bloodtest results immediately rang alarm bells in my doctor's head and after a Bence Jones urine test too I was referred to a specialist within 24 hours. I then had a bonemarrow biopsy that confirmed suspicions and my CTD treatment started the next day.
As Jean said, there's no point telling you not to worry because you naturally will BUT even if myeloma is definitely detected, don't go into an instant decline. There's so much that can be done to help you and after treatment you'll hopefully bounce back as well as I did.
Let us know how things go.
