Gary, the thumping began a few years ago. It eventually morphed into an even noise with a lot less thumping. It took about a year for the thumping to diminish in this way then one day it was just gone but replaced by a low steady rumbling that also gets worse when I move about. I have other sounds as well. They are mostly in my head but I hear them in my ears. Hope yours just goes away but it does seam to take patience.
