NSAIDs reduce pain, inflammation and swelling while helping the body return to a normal temperature. When the body is injured or ill, it releases an enzyme known as COX. NSAIDs help control two specific types of COX enzymes, COX-1 and COX-2.
If you have an outer ear infection or a middle ear infection, your ears may be filled with a fungal or bacterial infection. This will likely temporarily affect your hearing and may make your hearing sound muffled in the affected ear.
Excess mucus running down your throat may also make you feel hoarse and give you a sore throat. If the mucus plugs up the Eustachian tube -- the tube that connects the throat to the middle ear -- it can lead to a painful ear infection.
