Your immune system does need some work but first things first. Go with the high saline solution. Did you ever do that as a kid? Put salt on an insects back. They shrivel right up. Put it in your ears. You can use table salt if that's all you have but do it right now. High salt solution. Put 2 teaspoons of salt in about 4 ounces of water. Swab the ears with q-tips or better yet get an eyedropper and drop a few drops in the ear. It kills the bugs almost immediately.
There is even a high salt regime for internal parasites that has been very successful with the lymes disease parasite.
Hydrogen peroxide also. Bugs hate the high O2 levels. But I'd go with the high salt first.
Get Barefoots DeWormer going in on the inside use the high salt on the outside.
