many years ago i used to get terrible earaches and would often put cotton wool in them - trouble is, i ended up with what the doc termed 'soggy ears' - much like how your hands and feet go crinkly in the bath, or when you wear a plaster on your finger too long, even condensation - and this in turn made the earache worse
i would suggest only wearing it when outdoors or perhaps overnight, but give it chance to dry out when in the warm
