I've become interested in red light therapy and purchased a device that dispenses red and near-infrared light to promote healing. My MM has been quiet since my ASCT in 2021, thankfully! I'm 65, not taking any maintenance drugs. But I also have near-constant nerve pain and discomfort in both legs and feet from previous nerve damage, and also severe joint pain in both knees, hip and ankle, hence my search for treatments that might provide some relief. (I also receive acupuncture regularly). I've seen suggestions online that since red and NIR light increases energy uptake in cells and promotes cell growth (and healing), it could hurt me if it promotes the growth of malignant plasma cells in my bone marrow -- the last thing I would want. Does anyone know anything about this? I'm refraining from using the device until I get more information.
