Why did the doctor give you antibiotics? If there's no infection, and frankly even if there is, they can cause problems and they won't fix damage to an ear drum. Did you take her to an ENT or a regular doc? An ENT can look at the ear and tell you if in fact there's damage that won't heal. As any doc will tell you, don't let anything smaller than your elbow get anywhere near the ear drum. I'm just wondering why potentially damaging antibiotics would be given unless the doctor found the problem was an infection of some kind, and that's not damage to the eardrum.
