I have been having "mono signs" (with no exposure) for almost 5 years: sore throat, severe fatigue, flu like condition without fevers. It is cyclical, lasts 3-5 days to the point I am in bed for days. I have given up most of my gym/exercise activities because I only have about 4 hours a day of productive time. I have seen internal and family doctors, endocrinologist, infectious disease, urology. So far they do not know why I have persistent: low blood count, high IG Immunoglubulin labs (700s) and kidney stones with bloody urine (that does not cause bladder infections). I am over 50, normal weight/BMI, normal blood pressure, normal blood sugar etc. but does not know who else to see. I get my annual physical with no other abnormal labs or tests. I'm not a hypochondriac and being dismissed with menopause does not seem to fit my condition. Need guidance to thrive, not just to stay alive. Thank you for your time.
