A 32-year-old male surfer from Australia presents with recurrent ear infections. He has recently moved to the US and is generally healthy. The patient complains of difficulty in removing water from his ears after a shower and left ear discomfort. Upon examination, there appears to be an object protruding into the canal in the left ear, obstructing a clear view of the tympanic membrane. The right tympanic membrane appears normal, and there is no inflammation in either canal. What is the probable diagnosis?
