Bless your heart!
Ear infections can make you absolutely miserable. I agree with everyone--try one of those walk-in clinics and ask the doctor for a generic antibotic if he prescribes you antibotics. Places like Wal-Mart and K-Mart will fill some generics for only $4.00.
Home remedies to make it feel better-warm, not hot, compresses to the ear--very soothing. My grandma always used to make use put "sweet oil" in our ears when we had an ear ache. However, as an adult I found "sweet oil" is just olive oil--yep, just like you cook with so I DO NOT
I know what its like to have to have treatment without insurance. Years ago I had to have emergency gall bladder surgery without insurance--no choice. The hospital would only keep me a total of 23 hours-12 hours in the emergency room, then 11 hours in surgery and recovery room then I was out on the street being sent home. I survived. But it took me three years to pay off my hospital bill!
Hope you feel better soon!
