AB Orchitis  has  a  variable  onset  and  ranges  from  mildly  uncomfortable  to  severely  painful.  It  is  most  frequently  a  complication  of  epididymitis,  but  isolated  orchitis  without  epididymitis  can  be  caused  by  mumps  infection  and,  more  rarely,  other  viruses.  Mumps  orchitis  occurs  4  to  7  days  after  parotid  symptoms  with  testicular  pain  and  swelling.  It  is  unilateral  70%  of  the  time  with  a  contralateral  infection  developing  later  30%  of  the  time.  The  testicle  is  swollen  and  tender,  sparing  the  epididymis.  The  overlying  scrotal  skin  can  be  edematous  and  erythematous.  Constitutional  symptoms  of  malaise,  headache,  myalgias,  and  fever  are  common.
