Create a second group of participants with ear infections who use 15 drops a day

Have participants put ear drops in both their infected ear and healthy ear​

Answer 1

Answer:

Have participants use ear drops for only one week.

Explanation:

A middle ear infection, also known as acute otitis media, is an inflammation of the air-filled area beneath the eardrum where the small vibrating bones of the ear are located. Ear infections are more common in children than in adults.

Since ear infections frequently go away on their own, pain management and problem-monitoring may be the first steps in therapy. Antibiotics may occasionally be used to treat infections. Multiple ear infections can be a frequent problem for some people. This may lead to major issues including hearing loss.

Symptoms

The signs and symptoms of an ear infection often appear quickly.
