Dear Friends, I was diagnosed with MGUS in 2015, then watch-and-wait light-chain SM, with labs every three months. MGUS was discovered when presenting with skin sensations and balance issues, which have persisted, the balance problems getting worse, so that I now use a walker and cane. Other than old age, 85, the source of the imbalance is a mystery. Brain and ears have been imaged and Parkinson's has been ruled out. My understanding is that smoldering, like MGUS, generally has no physical symptoms. I'm wondering if you have heard otherwise from medical sources and whether you have balance issues that have been attributed to smoldering myeloma. I know I have to live with the mystery (and the falls and near-falls), but I'd love to expose SM as the culprit! Thanks much for reading and responding.
