At Little Spurs, we can evaluate and treat for ear infections. When a child develops a cold, the Eustachian Tube can become plugged so the fluid that normally is drained does not know where to go. The fluid can easily become infected with bacteria. If the ear drum is pushed out rapidly, your child may have ear pain. If the ear drum is not bulging, there may be no or very little pain. Despite starting treatment for an ear infection, the ear drum still can rupture causing drainage to come out of the ear. There is no way to determine when an ear infection started.
