Well, I absolutely did not mean to scare you. As I've said, I have done H202 in my ears for years, and despite what others say, I think they have kept more ear infections, which I suffered from for years, away. I'm pretty sure of it. A lot of bacteria resides in the ear, and H202 definitely kills it.
As far as CS in the ear. I've done this before without the result I recently had.
