A build-up of earwax or an object stuck inside the ear can sometimes cause earache.
If there is something in your or your child's ear that seems be causing pain, don't attempt to remove it yourself. You may push it further inside and you may damage the eardrum.
If you have a build-up of earwax in your ear, your pharmacist will be able to recommend eardrops to soften it so it falls out naturally. In some cases, your GP will need to remove the wax (once softened with eardrops) by flushing the ear with water. This is known as ear irrigation.
If there is an object in the ear, your GP may need to refer you or your child to a specialist to have it removed.
