As a child I would get blistering earaches with seemingly no rhyme or reason. Until I found the secret to alleviating the ear aches.
All you have to do is ﬁll a water bottle with hot water and hold it against the ear that hurts for around ten minutes and the problem will clear right up. And if it is both ears either use the same bottle for both ears, ten minutes each. Or just fill two bottles, one for each ear.
