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.
Eustachian tube dysfunction happens when the tube between the middle ear and the back of the nose (the Eustachian tube) doesn't work properly. This means that the pressure in your ear can't go back to normal. The result is muffled hearing and a popping or crackling noise in one or both ears.
