Should I Be Concerned

A year ago, I was sent to a nephrologist for hematuria, creatinine clearance by Cockcroft-Gault of 52, creatinine 1.24. He did some blood test that showed free kappa 30.7 (3.3-19.4), free lambda 18.1 (5.7-26.3) and ratio 1.7 (.26-1.65) interpretation states suggestive of MGUS.
I have history of peripheral neuropathy, night sweats (? Menopause causing), osteoporosis, (fractured wrist after fall requiring plate and 8 screws) have had a spinal fusion due to nerve compression, always fatigued and walking short distances (mowing lawn 30 minutes) tired, weak legs (feel like rubber bands) after just picking up sticks in the yard, and recently bruising very easily (don’t know how getting most of them) and cold sores that haven’t had since being on daily meds. I also have history of lymphocytic colitis, always thirsty so urinate frequently, nocturnal 2-3x a night, not losing weight though, short of breath after activity but likely out of shape. I am a 61 yo white female, BMI 28.2. Several ortho surgeries for nerve compression in foot, ankle, knee, elbow, lumbar/sacral area and shoulders, hip replacement. Wondering if should make an appt with ?.
