Hi.. Can understand your concern.. As per your complain Mumps also known as Epidemic Parotitis is a VIRAL infection and it can affect either one side or both sides Parotid glands which are major salivary glands leading to the above explained symptoms.. Although mumps generally occurs once only and recurrence symptoms are milder than the previous infection.. So it can be probably a recurrence of mumps.. There is no exact treatment for mumps and only symptomatic relief can be provided.. For pain you can take Acetaminophen or tylenol for relief.. Doing cold compresses can be relieving.. Take plenty of fluids which can include water,fruit juices,soups etc.. Take a soft and nutritious diet.. Take sufficient rest.. In case if the symptoms persist for more than 10 days without any relief you should consult a physician.. Hope this information helps.. Thanks and regards.. Dr.Honey Nandwani Arora.
