Hello, thank you for communicating with us for your problem. As per the brief history you have given us it cant be mumps
as the immunity is developed against the infection. and further i would suggest you not to get tense as there will be investigations before the surgery that will clear your doubt. tell the treating doctor about this infection. Please don’t hesitate to consult and ask for any more queries. I will be pleased to answer.
With best wishes for a speedy cure
