I had very itchy ears for years, itched more after I cleaned them. Now I have realized the itch is from pinworms. I put oil of oregano or tea tree oil on a wet(water) Q-tip in each ear at night.(just a drop or two), you need to wet the Q-tip with water to dilute the oils or they will sting. The next morning I have a few dead pinworms just inside my ears. I have been doing this for about a year now. The itching has left and the terrible ringing is gone. I still do this because I am still getting the dead pinworms, when I no longer get the pinworms I will do a maintance, once or twice a week. You can also put the oils on a damp cotton ball and place inside your ears all night.
Hope this helps you, heyjude
