I have been dealing with health issues for 4 years now. Before March 2019, I was a life long athlete, marathons, triathlons and Ironman and within a few months, I could only walk short distances, difficulty with stairs, no balance, weak muscles, no reflexes and the list goes on. I was first diagnosed with Guillan Barre Syndrome followed with 50 IVIG treatments which ended up being the wrong diagnostic. Then 2 years ago I was diagnosed with IGM paraprotein neuropathy, later, Anti Mag Neuropathy and now DADS-M with Anti Mag with MGUS. How rare is that. Three different diagnosis with three different neurologists. I had 4 rounds of Rituximab within a month 2 years ago with no improvement. My Oncologist suggested I try Rituximab every 3 months for one years see what happen. After 3 treatments, still no change but they tell me to be patient as well. Three years of physical therapy helps me with my balance. I wish I could do more exercise but I can't do anything that involves my legs. I do rowing, handcycle, swimming and upper body weights. I feel there is more to it because now I have memory, cognitive and speech issues following a double lung embolism. I have more symptoms but the list is too long. I am 62 years old and feels like 80+.
