Although kidney stones often do not cause any symptoms, there are 5 signs that burning after urination/penile burning after sex could be caused by kidney stones.
Burning after urination or penile burning after sex may be caused by several medical conditions, such as a urinary tract infection or a sexually transmitted infection like gonorrhea or chlamydia. But if the cause for the burning sensation is kidney stones, you may experience the following signs:
Persistent urge to urinate. You may feel the need to urinate more often than usual and will feel the penile burning each time.
Pink, red or brown urine. This is a sign that there is blood in your urine caused by a kidney stone traveling down the ureter. Your urine may also smell bad or look cloudy.
Pain in the back that spreads to the lower abdomen and groin. If the kidney stone is large, it will cause pain starting in the kidney and as it travels down the ureter into the bladder. You may also feel pain when urinating.
Nausea and vomiting. These symptoms may accompany the pain caused by the kidney stone.
Fever and chills. The kidney stone may cause you to get a urinary tract infection, which in turn will cause you to have a fever and chills.
Most kidney stones pass out of the body without help from a doctor. But some are large enough to get stuck in the urinary tract, block the flow of urine and cause an infection. In this case, you should contact your doctor immediately.
