What is the pain when urinating?

There are many reasons for pain when urinating, but the most common is inflammation, that is, inflammation of the urethra or bladder, which is often said to be cystitis, urethritis or urinary tract infection. This reason is the most. Because in the process of urination, bladder contraction is needed, and the urethra is open. In the entire mucosa and tissue of the bladder and urethra, if there is damage or the most common inflammation, the urine flow during urination can stimulate the mucosa of the bladder and urethra, causing pain. If only occasionally one or two times of urination discomfort, no frequent urination, urgency or hematuria should not be a problem. But if frequent performance, every urination is like this, not only when urination will be painful, but also there will be increased number of urination, urination a little unbearable, sometimes there is a sense of urine, that is, always feel after the discharge is not clean. At this time we should go to the hospital to do urine routine examination, see if there are other problems in the urine, there is inflammation.
