Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have lump on uvula along with fever is because of bacterial or viral infection of oral cavity. Probably you have developed Canker sores which is causing you high grade fever as well as uvula acts as a barrier to swallow food and prevents bacteria and infections from entering the throat and digestive tract. I would suggest you to drink a glass of warm water with honey to reduce the swelling and prevent the spread of any infection. Do warm saline gargles. If the underlying cause of the condition is a viral or bacterial infection, the appropriate medication should be taken. Antibiotics will help get rid of a bacterial infection and over-the-counter painkillers or anti-inflammatory drugs may help with a viral infection. Chew two to three cloves of garlic to help reduce the infection and heal an enlarged uvula. Fresh onion juice is also an effective remedy. You symptoms will resolve in 3-5 days. If your condition keeps on persisting visit general physician once and get it examined properly. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
