An excellent folk remedy and something that provides immediate relief is hydrogen peroxide, especially for ear infections! Here's how to effectively use it: lay on one side, with a towel wrapped around your neck, your infected ear upwards, and pour a capful of the liquid into your ear canal (or have someone else do it, it's quite disconcerting at first). I find the fizzy, bubbly sensation enjoyable although you might not like it. When the liquid becomes warm to hot, which it should if you have a bad infection, simply tilt your head over and dump the liquid into the towel. Keep doing that until the liquid does not bubble or become warm, and then clean your ears (or have a nurse do it, but who actually goes to the trouble).
Hydrogen peroxide mixed with water also makes a great mouthwash.
Hope your health improves!
My mother always used this with me as a child, and it worked splendid.
