Ear infections cause pain, swelling, and sometimes fever or discharge. Most affect the middle ear and can be treated effectively when caught early.
It's no surprise that the constant, nagging pain caused by an ear infection can limit your ability to sleep. To make matters worse, ear infections can cause a ringing sensation in the ear, further impeding a good night's sleep.
Symptoms can also worsen when lying down, making it particularly difficult to get through the night. If you experience other symptoms at night, including fever and restlessness, you may have an ear infection.
