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.
Ear pain occurs when the Eustachian tube that runs from the middle ear to the back of the throat gets blocked. The Eustachian tube drains the fluids that is produced in the middle ear, so when it is blocked the fluid builds up, leading to pressure on the eardrum and the consequent pain.
