To help relieve your fever, body aches, and pain, you can take over-the-counter medications like paracetamol or ibuprofen. Please follow the package instructions carefully. Getting plenty of rest, staying hydrated, and gargling with warm salt water can also ease your throat discomfort. Because you are experiencing ear pain alongside a severe sore throat, it is highly recommended to see a doctor. These symptoms can sometimes indicate a bacterial infection, such as strep throat or an ear infection, which may require prescription antibiotics. A quick evaluation will ensure you get the correct treatment to feel better soon.
