Hello, Welcome Thanks for consulting HCM,
I have gone through your query, as you have mentioned that you have blockage of
salivary gland since long time ,now you are feeling
fever , yes it can be due to that or may be due to viral infection also,
Dont worry go to
Dentist and get investigations , Sailography done and go for proper treatment ,
For fever you can take medications One Tablet
Paracetamol three times a day for 5days ,
One Capsule vitamin B complex once daily for 5days ,
Then go to Dentist and get treatment done.
Hope this will help you.
Wish you good health.
