Hi! Welcome to Healthcaremagic. I read your query. You have not mentioned the location of swollen glands like lower jaw, behind the ear, etc. Swollen salivary glands can be due to various causes like Bactrrial or viral infection, stones, cysts, autoimmune, etc. I suggest you visit a dentist for check up. You need to provide history like recent infection, medication history, any radiation exposure, etc. Get blood test done for infection. X ray of salivary gland or Sialograpgy can be done if needed. Meanwhile, you can start with the antibiotic course on prescription. Tylenol or Ibuprofen will ease pain. Maintain good hydration. Warm compresses of swollen area will help. Chew sugarless gums for stimulating saliva. Sialadenitis, i.e. infection of salivary glands starts regressing after 48 hrs with antibiotics. But stones or cyst or other complications need further treatment. Hope the answer helps you. Thank you!
