Mastoiditis in children and adults is inflammation and/or infection of the mastoid bone, which is located behind the ear. The most common cause of mastoiditis is an inner ear infection or otitis media. Acute mastoiditis lasts for a short period, while chronic mastoiditis can last for months to years.

Symptoms of acute mastoiditis in children and adults include, pain and swelling behind the ear, pus draining from the ear, and a low-grade fever. Complications of mastoiditis include meningitis, abscess, dizziness, and conductive hearing loss.

Mastoiditis requires antibiotic treatment so it cannot be treated at home with natural products or home remedies; however, home remedies may help reduce symptoms of pain, inflammation, and fever. Some individuals will need surgery to cure their infection.
