I went to my PCP Monday. I have had pain in my lower back, like a kidney stone, that radiates up into my rib cage for the last few weeks. She ran blood work and sent my urine to the lab as there was protein and blood in it. She also ordered an ultrasound to see if it was a stone, as I have a history of kidney stones. No blockage and no stone in the right, 3 mm stone in left kidney that has been there since 2004. I have also been running a low grade fever and I feel like I am swollen, mainly my fingers, face? I asked to have my labs sent to me when the were complete. Everything was normal with the exception of the following: High level, MCH, Hemoglobin, MCV, MCHC, #Neut, Segs. Also low level Lymph. The urine sample showed no pathogens isolated, mixed skin flora, probable contamination. Does this mean that I have an infection? Should I repeat the urine sample? I also was diagnosed with SLE in November. The pain is over an 8 right now.
