My husband was diagnosed with transverse myealitis after a 4 year journey as well as MGUS a blood disorder. Somewhere he was told to take extra vitamin b12 and was told by hematologist his number was too high. It's difficult when you have 2 neurologist a nephrologist a rheumatologist and a PC to get them all on the same page. Does anyone have experience with b12 and if it helped them or not?
