Yes, myeloma starts in our bone marrow. It can manifest on the skin. It needs evaluated by your doctor.

Mine was on my thumb also. It stuck out like a hard bone. It was also painful. Fortunately it gradually goes away, if it is Bouchard’s node.

Joseph,
Please call your doctor. I have had painful boney growths stick out on my hands. They come and go. They are called Bouchard’s nodes. I have osteoarthritis. Don’t assume you have this. Get checked.
