Hydrogen Peroxide is a miracle worker. I suffer from constant ear infections, as an adult I have tubes.
A few things I do when I have a bad flare up- they even affect my jaw and neck!
First, I put HP in my ear- I just lay on the bed on my side. Drop it in and IF you do have infection it will bubble and fizz. Often, for quite some time. It doesn't hurt, but its kinda like having pop corn in your ear! When the fizzing stops, then I put some fresh garlic in olive oil and warm it up. WARM, just a bit warmer then room temp. Your skin there is very sensitive and can burn. I put that in.
Then, I will wave a blow dryer around my ear, that seems to help dry things up and take away the pain.
I will also take a good anti inflamatory. Personally, I use naturopathic only.
I find the peroxide is a miracle worker. As soon as I think I am getting an infection of ANY kind I do that. Even if its a sore throat and I think I am getting a cold. I haven't been sick and/or had a full blown infection requiring antibiotics in over 3 years, since I started this. My 4 year old daughter is never sick either!
I hope that helps give you some relief until you can see your doctor.
