I agree with woofgang - I look in ears for a living (Hearing Aid Audiologist) and the HAC (hearing aid council) rules are that we have to report to a patients GP if they have had ear ache for 7 consecutive days in the last 90 days. So you would be best waiting for it to pass - but see your doctor if it lasts more than a week
if you feel like you have water or something inside your ear go to your GP or walk in centre, I suffer from them often, they give drops that are great, they really help, or get olive oil on a heated spoon and pour in your ear that helps soften wax.
