According to the National Kidney Foundation, "more than half a million people go to the emergency room annually for kidney stones." The Foundation states, "The prime age for kidney stones is between the ages of 20 through 50."

Men and women both suffer from kidney stones. However, men are twice as like to have kidney stones. African-Americans are less likely to suffer from kidney stones.

Symptoms for kidney stones are the same for both men and women. Since some women have a higher threshold of pain, some women may ignore their symptoms and classify their pain as menstrual cramps, back pain or sore muscles.

Additional symptoms of kidney stones include:

• Nausea
• Vomiting
• Fever
• Chills
• Urine that smells bad or looks cloudy
• Burning feeling when you urinate
• Severe pain on either side of your lower back
• More vague pain
• A stomach ache that doesn’t go away
• Blood in your urine
