The fact that you were taking medication for back injury has nothing to do with the appearance of blood in your urine. If the back injury has cleared up it is best tat you see a doctor as soon as possible. The appearance of blood in the urine system is a serious warning sign of something that is growing wrong in your body and if left untreated will definitely lead to further complications. You will not be able to deal with this yourself or without the help of proper medical advice as it is next to impossible to detect what is causing the appearance of urine in your blood stream. The best and safest way to tackle the problem is talk to your doctor about in order to determine what the best course of treatment is.
One of the most common reasons of the appearance of blood in the urine system is caused by a kidney stone. This generally happens because irritates the ureter and cause the formation of blood. But all cases of blood in the urine are not always kidney stones. Therefore either way there is no further way of telling whether the blood is caused due to a kidney stone infection or due to another reason.
