I have had an itchy ear for a few months...its one of those deep intense itches where you could find yourself scratching it extremely hard for minutes on end. I had tried h202 and turpentine mixed with castor oil, both with limited, temporary relief. Decided to try some DMSO today. Eureka! The itch appears to have disappeared. I used a 70% blend with 30% distilled h20. Soaked a q-tip and rubbed the inside all the way down the canal. I don't know why I didn't think of this before! So please list DMSO as a viable solution, and thanks Diedre for all you do.
