Thank you, Cathy, I will keep you informed.

Please do!

Susan, I hope that you don't have to endure another bone marrow biopsy. I had one as well and you're right; they are no fun at all!

I actually seen my oncologist today for the MGUS Protein and he is doing some checking to see if there are any changes in my levels if they are high, it will mean bone marrow biopsy, I have had two of those and they are no fun

I believe that your reading is correct. Since it is thought that PN may be associated with the immune system and the immune system involves immunoglobulins, it could possibly be the reason. If it is concerning to you, it may be a good idea to schedule an appointment with a rheumatologist or an immunologist. If you review some of the medical literature available online such as Mayo Clinic, Cleveland Clinic, etc., they will provide further information on MGUS. All the best.
