My Ears Here Lately Have Been Feeling Nu.b And Then

My ears here lately have been feeling nu.b and then they go to sleep...can you tell me why
..also that both feel heavy at the same time and they g o to sleep at the same time I believe there is a reason but I need to know what causes this...I have had cancer and I suffered from an aneurism too so I don't know if this is a problem from that or if there is something new to worry about
