I sleep with earplugs and cannot stop it .since last month i get frequent earaches.ent said mild external otitis and gave me eardrops and 2 weeks later that it hurt again celestoderm ointment for mild irritation.now it hurts again.what should i do?

The old saying "if it hurts when you do that quit doing that" applies. For whatever reason the earplug habit is triggering painful problems. Pausing the habit for a few weeks may be all that it takes for the skin of the inner to heal with whatever meds are used. It may heal enough that you can resume the habit, or this may be a long term problem.
