I think you might have an ear wax plug.

Ear plugs can cause wax blockages. Wax is produced in the last 1/3 of the ear canal (the end near the outer ear). The ear plugs (Q-tips, ear buds, etc.) can push wax further into the canal where it hardens and remains. This can hurt. Tinnitus, a sensation of fullness and loss of hearing are common symptoms.

If you pull on your earlobe does it feel better? Sometimes this can help relieve the discomfort, caused by wax buildup. It worked for me.

Ear plugs don't contact the eardrum unless they are too small and forced into the canal, that is about 3 cm long. Small objects, loud noises, infections, head trauma and pressure changes (airplanes, scuba diving) can cause the eardrum to rupture. Have you experienced anything listed here, lately?
