I have Parkinson s which has not been responding to meds. Over 3 months I have had 20 lb weight loss, proteinuria, hematuria, low blood protein, orthostatic hopotension, gastritis, sensitivity to odors causing respiratory response and extreme fatigue and muscle fatigue. I just had an infected gall bladder removed but my symptoms are not improving. I have had 24 hr urine which showed protein of 20,000, normal ct scan of abd. except for gall bladder, normal kidney sonogram, fairly normal labs except for low protein. What could this be?
