I wear large ear plugs every night to bed. 33 decibels. My ears are itchy everyday. Should I be concerned! And long term effects with wearing?

There are some risks. associated with prolonged ear plug use including suboptimal draining of ear wax. This may lead to ear wax impaction with associated tinnitus or ringing in the ears. There may be a small increased risk of ear infection. Regularly clean ears to encourage earwax removal. Make sure your plugs are clean; replace them regularly. Your itchiness may be a sign of some of these problems already.
