Groin pain in men is often a result of injury or a pulled muscle due to sports, according to Mayo Clinic. Less common causes include kidney stones and diseases such as epididymitis and hydrocele.
A very common cause of groin pain in men is a pulled ligament, muscle or tendon, states Mayo Clinic. This often happens in athletes who play contact sports such as hockey, football and soccer. The individual may experience the pain immediately after the injury, or the pain could increase gradually over a long period of time. Groin pain due to an athletic injury may worsen if the person continues to use the injured area.
Groin pain in men may be due to a kidney stone or a hernia, reports Mayo Clinic. Testicle conditions may cause pain that radiates to the groin area. Other less common causes are testicle tumors and enlarged lymph nodes, according to MedlinePlus.
Conditions that may directly or indirectly cause groin pain in men include hydrocele, or swollen scrotum, testicle inflammation or spermatocele, which is the buildup of fluid in the testicles, explains Mayo Clinic. Men also may experience pain and discomfort in the groin area due to a twisted testicle or a retractile testicle.
Men should contact their doctor if the pain lasts for more than a few days, advises Healthline. If the groin pain is accompanied by blood in urine, fever, or swelling and lumps in the testicles, he should seek immediate medical care as these symptoms could indicate more serious conditions such as testicular cancer or infection.
