The cause of<unk>  is a large amount of blood circulation to the genital area, specifically the penis and testicles, without the release of tension associated with orgasm/ejaculation. When a large amount of blood flows to the genital region, the penis becomes erect and the testicles also experience increased blood flow and swelling. Other causes of painful symptoms include: * diabetic neuropathy in the groin area * epididymitis, which is an inflammation of the testicles * infection, which is usually accompanied by inflammation * kidney stones * mumps * orchitis * testicular cancer * tight trousers It may also be a sign of testicular torsion, which often requires emergency surgery.
