For the past two years I have had on-off problems with fluid buildup behind my eardrum. I've read that sucking a pacifier can cause fluid from the throat to enter the ear, and last night when I was sucking my thumb I started to get that pressurized feeling in my ear. I've been to doctors and the only thing that seems to help it is a cortisone shot. (My ear, nose, and throat doctor recommends tubes only in very severe cases.) But while it may be the cause of the problem I could NEVER give up my paci! Anyone have similar experiences?
