My age is 49years. Male. I have a resounding sensation in my left year (as if some air is passing in left ear). This will not be through out the day. Usually resounding sensation starts after 10 AM and will be up to 2 PM. I will take breakfast around 9-10 AM, lunch around 2PM & dinner at 8 PM. During period of resounding my voice also goes harsh (weak).This I am having since my childhood. During period of resounding my presentation of lecture will have weak voice. I observe that if I consume more salt this sometimes disappear. Pl tell the cause for this. Pl suggest me how to overcome it.
