An ear ache is the most painful pain in the world. I think in the "Home Remedies" book I had years ago it said to blow a warm hair dryer down the ear shaft. The warm air will also soften and thin out the goo so it can drain.
If you have children's sudafed give her half a dose. It will thin the goo out some and may allow the infection and dry goo to drain accordingly.
In the chiropractors office the use a massager and push from the bottom of my ear down towards the collar bone/sternum area. This helps the goo to move towards the throat out of the Eustachian tubes.
I truly would take her to the ER if nothing is working though because ear pain is a sign that there is too much stuff behind the ear drum. It needs to start draining. If she isn't treated with antibiotics it can make her deaf like it did my grandson. The ENT went in to put tubes in to see if that would help him hear even a little bit and he found debris from past ear infections that the antibiotics never treated. He cleaned the ears out and my grandson can hear normally again. IF he had seen an ENT when he had the ear infections he might have received the correct antibiotics. The pediatrician did not prescribe the correct ones.
I asked the pharmacist afterwards and he said the antibiotics the pediatrician had prescribed were general ones that were good overall but not really worth anything for the ears or other internal/enclosed areas.
Make sure to ask the pharmacist if the right prescription is what you have been given. Specifically for ear infections. If it's the white augmentin I can't get a kid I have ever had to swallow willingly when they taste it so you might see if there is anything else.
