He sometimes become mad in sleeping times. He get up and sits here and there arround bed and lie in different position of neck . And this keeps up to one hour. His sleep is affected and also he kept fingering inside either one ear. Only one ear problem occurs at a time. Both ears have stong wax build up. I have attached image . Pls suggest what to do.
