Flu + Blood in Unrine?

I have had the flu for the last five days. It started with aches, chills, a low grade fever, and nausea. I went to the doctor and he told me I had the flu and to expect things to get worst then better. My symptoms have continued with some chills, a constant low grade fever (99-101), no appetite (I force myself to eat), nausea when I do eat, and now a sore throat and cough. Tonight I started peeing blood. My father insists that I need to watch my temp and if it goes up to go to the ER (right now it's at 99.5), but what could be causing all of this?

You should go to the ER dear. If you are peeing blood then you have some sort of infection going on. You should be feeling some better by now.

NO! Blood in your urine is a serious indication that something may be wrong with your kidneys!!!! That is NOT a symptom of the flu!!!!!!! The fever can be an indication of serious infection internally. You sound septic. Seek an ER immediately!!! EMT advice.....

The well-known causes of blood in the urine include the following:

Kidney stones


Infections of the urinary tract or genitals


Blockage of the urinary tract, usually the urethra - by a stone, a tumor, a narrowing of the opening (stricture), or a compression from surrounding structures


Cancer of the kidney, bladder, or prostate


Kidney disease


Blood clotting disorders


Injury to the upper or lower urinary tract, as in a car accident or a bad fall


Medications - Antibiotics [for example, rifampin (Rifadin)], analgesics such as aspirin, anticoagulants [blood thinners such as warfarin, (Coumadin)], phenytoin (Dilantin), quinine (Quinerva, Quinite, QM-260)


Benign (noncancerous) enlargement of the prostate - known as benign prostatic hypertrophy (BPH), a common condition in older men


Chronic diseases such as diabetes, hypertension, and sickle cell anemia


Viral infections Flu


Inflammation of the kidney - usually of unknown cause


Strenuous exercise, especially running - results from repeated jarring of the bladder
Sometimes no cause is found for blood in the urine.

If serious conditions such as cancer, kidney disease, and other chronic diseases that cause kidney damage or bleeding are ruled out, the cause is usually not serious.


The hematuria will probably go away by itself or continue as a chronic condition without doing harm. Any changes should immediately trigger a return visit and evaluation by your healthcare provider.
Urine can be colored pink, red, or brown for reasons that have nothing to do with bleeding in the urinary tract:

Foods - beets, berries, rhubarb in large amounts


Food coloring


Medications - Certain laxatives and pain medications


Menstrual blood


Liver diseases - also can be very serious

Hope this helps
