Kidney stones are a common cause of groin pain, according to Healthline. Other common causes of groin pain include hernias and muscle, tendon and ligament strains. Less common causes of groin pain include testicular inflammation, a pinched nerve, urinary tract infection and enlarged lymph nodes. Individuals suffering from groin pain should seek immediate medical evaluation if they experience bloody urine, fever, pain that spreads to the chest, back and abdomen, or fever.
Kidney stones are hard, small deposits that form in the kidneys, states Mayo Clinic. Made of mineral and acid salts, kidney stones can affect all areas of the urinary tract. Although passing kidney stones can be extremely painful, these stones do not typically cause permanent damage.
In addition to pain that spreads to the groin and abdomen, other symptoms of kidney stones may include nausea and vomiting, a persistent need to urinate, painful urination, cloudy or smelly urine, and chills and fever. Some people with kidney stones experience pain in their back and side, underneath the ribs, notes Mayo Clinic.
Types of kidney stones include calcium stones, struvite stones, uric acid stones and cystine stones, explains Mayo Clinic. Calcium stones in the form of calcium oxalate are the most common type of kidney stones. Struvite stones develop due to an infection; uric acid stones form in people who do not consume enough fluids; and cystine stones develop as a result of a genetic disorder that causes the kidneys to excrete excessive amounts of amino acids.
