I have been feeling ill, night sweats, severe muscle cramping in my back near my kidneys and lungs. I have been short of breath. Today I had a urinalysis done. Cloudy, protein: 0.15, hgb: 2, RBC 11-20. Calcium oxalate present. Casts present: rbc WBC. I have no appetite, I'm losing weight rapidly. My Bp was 90/60 at the doctor. My blood hgb was 155. My hct was high as was my rbc count. What's going on?
