Hi,
I don't mean to interfere in your conversation, but I would like to say a couple of things. First: because the mgus is the body working too much to fight infection/disease, it is not uncommon to have an autoimmune disorder along with the mgus. I have at least two autoimmune disorders. They can cause bone pain. For instance, fibromyalgia pain can feel like the bones are sunburned and also they can cause severe pain in little spots, or small areas.
I don't want to try to diagnose anyone. My oncologist tells me to watch out for severe pain when walking. And the levels of the markers in the blood is what is important. Most mgus doesn't turn malignant, but it is a 'blood tumor' and as such has it's own problems. The blood thickens and can cause bleeding in the eyes and other mucus membranes.
I have had this mgus at least five years, perhaps more as I couldn't get anyone to tell me what was wrong. It was causing nerve problems and this also leads to pain.
I don't know that I have helped anyone, hopefully I have not 'hurt' with my information. It is good to ask a lot of questions when you see your oncologist. They are the only ones who know you and what you should expect.
