I have been ill w/cmv for 8+ mos. now. All my dr. tells me is that it is a self-limiting virus and it should go away in 1 yr. at the latest. My IgM levels go up and down as do the severity of my symptoms. Dr. says there is nothing i can do to prevent these spikes or hasten my recovery. Does anyone out there have any info regarding herbs, new research, nutrition, or any other approach to pro-actively aid my immune system and help get me back in good health?
