A few months ago I noticed that deep inside my ears I had a constant 'itch'. I hadn't used my $!0.00 zapper for awhile.... after 'zapping' I noticed that they weren't itching at all anymore, and it has been several weeks now.
I've read that itching ears, can mean the presence of a type of parasite.
I have been using my zapper more consistantly... weekly... for 'just in case' I pick up anything I can get rid of it quickly! I do quite a few other things for parasite control. But zapping worked instantly for my itching ears.
My 87 year old mother has had itching ears for years, and along time ago she punctured her eardrums by trying to relieve the itching by using cotton swabs, etc. She has caused permanent damage to her ears and cannot hear without her hearing aids.
