Hey Heather,
Fear not...others hear the noises too!

I've been hearing them on and off for years. They range from the ocean sounds to saranwrap crinkling...kind of makes you crazy when they happen doesn't it?
My husband laughs at me. There are times when I say 'What?' and he hasn't said anything! DUH!
It does calm down some when the swelling is reduced...it isn't as bad after my surgery and it seems to be getting better every day...have no fear we share in the indignity with you!
Take care,
Jennifer
