I hope this starts to help you!
I dont know anything about candling, but just wanted to add something.
I was reading, that strep bacteria in the throat travels up into the ear thru the eustation (spelling) tubes. There are other types of bacteria as well. Yet I think strep is very common in ear infections. If you zap you can kill these pesky invaders.
If you consume dairy, sterilize it, boil all milk, bake all cheese ( until it boils, until it bubbles )
Check out Dr. Clark in this website- this has helped me with ear trouble.
I once burst a ear drum, after a severe sore throat and fever.
