My left ear has been deaf for four days and now it is painful and throbbing?

One, NEVER stick anything (including your fingers) in your ear. You probably made it A LOT worse. If you ruptured your eardrum, there would be blood and it would be VERY painful. I think you might need a doctor. It could be very serious. He would give you (might) ear drops to cope with the pain. If you have too much earwax, he might flush your ears out (it doesn't hurt, it sounds weird and might help you with the hearing part).
