Middle ear and outer ear infections are common causes of sharp ear pain. An infection of the inner ear, formally called labyrinthitus, may cause sharp pain as well as a loss of balance. People with a bad cold or the flu often experience sharp ear pain.
Still, if you have an earache, you might need to see your doctor for a diagnosis and proper treatment. While earaches can occur first with a cold virus, sometimes a secondary infection of the middle ear may occur. These ear infections are usually sudden in onset and extremely painful in the beginning.That's because the sensory nerve endings in the eardrum respond to increased pressure with pain.After the eardrum stretches a little, the earache pain may ease up. Other symptoms of an ear infection, or otitis media, may include the following: 1  Loss of appetite. Pressure changes in the middle ear as the child swallows, causing more pain. 2  Irritability. 3  Poor sleep. 4  Pain may be more persistent when lying down as fluid is shifting. 5  Fever. 6  Ear infections can cause temperatures up to 104 degrees F. 7  Vertigo. 8  You may have a sense of spinning. 9  Drainage from the ear.
