### input:
I had to have what my doctor termed emergency lithotripsy due to my vomiting and malaise.  I was recovering from a bout of whT was most likely viral  bronchitis as it was not improving with antibiotics, but with a nebulizer and prednisone ect.  I had litho in both kidneys and stent in the left that was removed at the end of procedure.  I awoke in agony only on the left side and my recovery has been very painful and slow with daily fever (usually in evening). Any where from 99.3 to 101.2.  My doctor showed no concern for the fever.  Finally after 2 1/2 weeks we insisted on a cat scan which showed my left kidney is twice the size of the right kidney and there is a large hematoma.  He still shows no concern for fever or this kidney.  He says it will resolve on its own.  I went to my primary doctor and she ordered chest X-ray and CBC looking for infection.  Every thing came back fine except my hemoglobin is low.  What could possibly be causing my fever?

### output:

Hi and welcome to Chat Doctor. Fever indicates some kind of INFLAMMATION somewhere in the body. Given your history and clinical condition, it most likely is emanating from the Kidney/ urinary tract. Not is always fever from infection, but it is the most common cause, so urinary infection or infection in the hematoma needs to be ruled out. I suggest you get repeat blood count (CBC), CRP, Kidney function tests (Sodium, Potassium, BUN, Creatinine), urine routine and urine culture at the earliest. You might need to start empirical antibiotics (unless you are already on one) until you get the results of the above. Hemoglobin is probably low since you have had bleeding and possible infection as well. Hope this helps. Regards. RB
