I was diagnosed last fall with MGUS. I had a cold in December and then sinus congestion/drainage for months. My doctor prescribed a daily rinse with a prescription drug and saline, plus flonase. Did not help much at all. Finally got an antibiotic last month. It helped a lot, although I still have periods of drainage on most days. It has NEVER taken me that long to recover from a cold.

While I have had exzema for about 6 years, it had been very minimal and was mostly on my lower legs and easily controlled. Last fall I got a hellacious rash that would start on my abdomen and spread up to the back of my neck and scalp. Prednisone is all that really helped. Can't live on that though so now I get twice a week light treatments.

I have also now have consistent upper body weakness which is mostly a problem doing discrete tasks like picking up a glass of water, etc. I can play pickleball and work in the yard without a problem. Last month I was also diagnosed with a hand tremor by my neurologist.

Not sure how all of this classifies as undetermined significance.
