ear infection....




EIGHT MAIN SYMPTOMS OF AN EAR INFECTION

  1. *Cold symptoms – keep in mind that ear infections are almost always preceded by a cold. Often a clear runny nose will turn yellow or green before an ear infection sets in.

  2. *Fussiness during the day or night

  3. *Complaining of ear pain or hearing loss

  4. *Night-waking more frequently

  5. *Unwillingness to lie flat

  6. *Fever – usually low grade (101º - 102º); may not have a fever.

  7. *Sudden increase in fussiness during a cold

  8. *Ear drainage – if you see blood or pus draining out of the ear, then it is probably an infection with a ruptured eardrum. DON'T WORRY! These almost always heal just fine, and once the eardrum ruptures the pain subsides.
HOW DO EAR INFECTIONS OCCUR

*Anatomy lesson. The ear is divided into three parts: the outer ear canal, the middle ear space where infections occur, and the inner ear where the nerves and balance center are. A thin, membranous eardrum divides the outer and middle ear. The middle ear space is also connected to the back of the nose via the Eustachian tube.

*Immature Eustachian tube. In infants and young children this tube is much shorter and is angled. It is therefore much easier for bacteria to migrate from the nose and throat up into the middle ear space. As the child grows this tube becomes more vertical, so germs have to travel "up hill" to reach the middle ear. This is one-reason children "outgrow" ear infections.

*Colds. When your child has a cold, the nasal passages get swollen and mucus collects in the back of the nose. This environment is a breeding ground for the bacteria that normally live in the nose and throat to begin to overgrow. Mucus is also secreted within the middle ear space just as it is in the sinuses.

*Bacterial invasion. Germs migrate up through the Eustachian tube and into the middle ear space where they multiply within the mucus that is stuck there. Pus begins to form and soon the middle ear space is filled with bacteria, pus and thick mucus.

*Ear pain. This pus causes the eardrum to bulge causing pain. It is this red, bulging pus-colored eardrum that the doctor can see by looking into the ear canal.

*Diminished hearing. The discharge that collects in the middle presses on the eardrum preventing it from vibrating normally. This is what the doctor means by "fluid in the middle ear." Also the fluid plugs the eustachian tube and dampens the sound like the sensation in your ears during air travel.

p/s :Repeated ear infections can also lead to hearing loss,OMG!
