I had a throbbing ear ache years ago, from teaching scuba diving, an old timer scuba instructor told me to put a few drops of boric acid a few times a day. It worked like a charm in a day and half the infection was gone. I used it for years when I felt the infection coming or after getting one and it always worked well.
Now I can not find the liquid solution anywhere!!! It used to be over the counter. It won' work with the powder, even if you make a solution. I hope this helps.
