what are mumps in testicles?
Pain and swelling of the testicle (orchitis) affects 1 in 4 males who get mumps after puberty. The swelling is usually sudden and affects only one testicle. The testicle may also feel warm and tender. In affected boys and men, swelling of the testicle normally begins 4 to 8 days after the swelling of the parotid gland.
