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.
It may be possible that blocked ears is a symptom of some underlying medical condition. Therefore, do not ignore your condition if it persists. Ear problems are often overlooked initially, but ignoring them for too long can definitely be a cause for trouble later.
