Here’s an old fashioned remedy. I suffered dreadfully from ear infections as a child and wished someone would have tried this on me, because the anti-biotics were horrible!
Fresh raw garlic, cut into the shape of the opening of the ear.
Wrap it in kitchen paper/tissue.
Rest in opening of ear.
Sleep with it. Doesn’t matter if it only stays in for a few hours.
Wait 24-48 hours and it should get better.
