Ear aches are typically indicative of an ear infection. An ear infection is caused by the building of fluid in the inner ear. Sometimes the fluid is fine and bacteria doesn't grow and it will go away on it's own - typically those don't hurt, they just can make it difficult to hear. If you feel pain, typically there is a lot of fluid and it is infected and cause the ear drum to bulge and creates pressure, pain, loss of hearing and can cause equilibrium problems, dizziness, etc. If you think that you may have an ear infection, I would see a doc and get treated - you don't want your ear drum to rupture which can cause permanent hearing loss. My niece and my best friend's son both had ear drums rupture within 24 hours of ear pain. It can happen quickly and cause bigger problems down the road. Both of my sons have had frequent BAD ear infections and subsequently required tubes. Good luck!
