Please help! It is really bothering me!?

My ear started hurting about two hours ago and I don't know what to do..I previously had a cold and a sore throat. My friend has been using this home remedy for years: putting equal amounts of distilled white vinegar and rubbing alcohol together, putting like 4 or 5 drops in, and leaving it in for about 5 minutes. Would that likely work or damage it? Her ear has been fine...thank you to everyone who answered!
