that depends what is wrong, likely you have got an ear infection and impacted wax, no big deal, they can syringe it out. You might also get a lecture about shoving things in your ear lol.
i had the same thing, Dr said to use oil for 2 weeks then syringe when the wax had softened, i couldn't bear to wait that long so i visited an holistic therapist and she used hopi ear candle to draw the wax out, didn't need to go to drs after that it was marvellous.
