I've had the mumps only on one side of my face, is it possible for the other side to show symptoms right after the other has healed?

Confusing issue: The swelling of the salivary glands can be caused by the mumps virus and can involve more one side than the other.The illness runs its course and after resolution you don't see the other side infected weeks/months/years later. The first infection gives permanent immunity.However, you can have non-mumps infections in either set of glands and if bacterial they may recur.
