Ear infection :
This would be the cause of infection that promotes the bacterial and viral action leading to swelling and the accumulation of fluid medically termed as otitis media. Ear infections are possible in all ages, although this condition is more common in children. There are several reasons why an ear infection might occur. For example, upper respiratory infections or allergies and sinus infections can cause swelling of the Eustachian tubes that connects the throat to the middle ear. The common signs include the ear pain, the ones wherein the child cannot hear properly, fever, and irritability, fluid sometimes drains from the ear. Other symptoms of dizziness or problems relating to balance can be brought in by some cases. According to the severity and type of infection, treatment may vary, and mild forms of infections may respond to time itself, though over the counter pain relievers might be used for relief of pain. Antibiotics will still be prescribed if this infection is caused by bacteria. More home remedies used include warm compresses. Other preventive measures might be having proper hand hygiene, avoiding smoke exposure, and timely getting vaccinated to reduce the chances of having an ear infection.
