Hello. I'm 34 yrs old and they are telling me I probably have MGUS. I recently was tested for autoimmune diseases because the SED rate (inflammation levels) in my body are way too high and have been that way for years. Upon investigating, they found a poorly defined band in the serum and urine (something about a M-Protein) and it's reactive with IGG and IGA (whatever that means). They sent me to a Heamatologist/Oncologist and they are doing more blood work along with a 24 hr urinalysis. Can anyone give me more insight to this issue. I'm 34 with two children (4 and 2) and my two year isn't in good health himself. So, as you can tell I'm scared because I want to be healthy to take care of my kids. I also have soft tissue rheumatism.
