The "whooshing" sound in the ears is apparently a common condition, more especially in older people. What I have been told is that it is caused by the "atmosphere" in the ear canal along with tiny hairs in the ear canals.
I have the condition myself, and it sort of comes and goes. I think it is somewhat akin to the "sound of the sea" that one experiences when he hold a sea shell to his ear. Actually, anything works here -- a cup or a drinking glass will produce the same results.
From my experience, one can TEMPORARILY stop the "whooshing" sound by sort of replacing the "atmosphere" in the ear canal. Here you simply blow warm air into the ears with a hair dryer. Use the dryer in the same way you would use it to dry your hair -- hold it at about the same distance and move it around as if drying your hair.
I don't know if this will work for you, and the sound will come back after a while. However, it might help you get to sleep -- generally enough time for this.
I first experienced the problem about this time last year. I checked with my doctor who said nothing could be done and to simply watch TV or something. Nevertheless, he sent me to an ear specialist and my ears were perfect for my age (70). He said the same thing as my doctor -- atmosphere in the ear canal along with tiny hairs.
After watching CNN about the young girl who came up with a simple solution to the "phantom pain" condition is soldiers (i.e., pain in a limb that has been amputated) I reasoned that there might be a simply solution to the "whooshing" problem. The girl discovered that if heat were applied to the end of the limb, then the message to the brain by the nerve endings at that point was simply "heat" and not sort of "confusion" that was interpreted as pain. She has subsequently applied for a patent for a heating device for use in artificial limbs so the soldier can be mobile.
Anyway, when my "whooshing" got very bad the other night while watching TV, I decided to see what would happen if I shot warm air into my ears. I had actually thought about this several times, but wrote it off as "ridiculous." To my astonishment, when I turned off the hair dryer the "whooshing" had ceased. I went to bed and slept with no problems. The "whoosing" did come back the next day, so I used the hair dryer several times.
As I say, it may not work for you, but there is no harm I can see in trying it.
