B26.0: Mumps orchitis

You have mumps. The mumps virus has also spread to your testicles.

Mumps is caused by viruses. With mumps, your face swells up in front of and behind your ear. Both sides of your face may be affected. Your face may then be painful. You may also get a fever.

The mumps virus has inflamed your testicles. There are two testicles. The testicles hang outside the body in a sheath of skin. That is the scrotum. If a testicle has been inflamed by the mumps virus, it may swell up. The testicle may then be painful, too. This testicle inflammation may make a person infertile.
