When my infection was at it absolute worst in my colon.. I had constant ringing in the ears... especially at night was terrible and it went on for months. I was harbouring a giant tape and giant Ascaris and didn't event know it until I started doing coffee enemas and they started thrashing around....
The only way to get rid of the ringing is to remove as many worms as you an from your colon, especially the big ones.
At the moment my colon is pretty cleaned up but I have scattering in the body but the ringing has gone.. that's after I discharged a large tape worm and a huge ascaris.
I wonder whether you have some big worms in your colon causing your ringing that you're unaware of. I've tried albenda twice for extended periods and have had some success with it... but its not a total answer.
If I were you I'd be taking a good herbal parasite cleanse and heavy dose it along with garlic and other parasiticals, olive leaf extract, oil of oregano, cysteine to break down the Ascaris skin or zymex etc. Hit them hard, but not hard enough to cause more scattering - its a very fine line and the line I crossed was using vinegar. I used a vinegar enema and it caused scattering.. so I would not recommend it to anyone.
Some people say pharmas will cause the problem to get worse.. i'm not sure whether this is true or not. I recently did Albendazole and it did nothing for the worms in my neck and the one that goes into my head which I think is a long thin ascaris. But these scattered smaller ones are not causing any ringing in my ears.... it was the huge ones in my colon that caused all the trouble... I think the tape particularly...
Have you tried a mega dose of CoQ10 4000 mg's with fat? This disloged my tape. You might have tape in you... most people do. Try that as well.
Also... you can use a TENS machine to herd them from your face and neck. I got this tip from another poster here at Curezone, Geritol. You put the pads at the back of your neck and it does stop them from entering from the back of your neck. At high voltage, Geritol believes you can also kill them. My TENS doesn't go high enough but it certainly stops them from entering my head when I'm wearing it. Its very good relief when you need it and they are particulary active and upsetting.
