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..
It is very much clear from your explanation that you have mumps..
The symptoms subside within 7 to 10 days after the symptoms appear..
There is no exact treatment for mumps and only symptomatic relief can be provided..
For pain you can take Acetaminophen
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..
Although after occurrence of mumps once the person becomes immune for lifetime and and relapse can be with very mild symptoms..
Hope this information helps..
Thanks and regards..
