I just got back from the doctor and they told me I have blood in my urine. I went to the doctor because I wake up after about 5 hours of sleep with some pretty serious back pain.... They sent me to get a cat scan but i havnt heard anything yet... Any ideas?
Kidney stones can be very painful but they are treatable. You can find out more about kidney stones here on HealthCentral
One thing you might want to do while you're waiting for an answer is starting to drin extra water to help move the stone (if that's what you have). You can find out more on the link above. Good luck!
There are a number of possible causes of blood in the urine, but with the back pain my first guess would be that your doctor probably suspects kidney stones. If that is it, they will be detected with a CAT scan.
