YES! I had a bad tingling right leg for about a month (on and off, when I'd sit in a hard chair, it would be HORRIBLE at church!) Then I hurt my arm shoveling snow and I started focusing on my arm (wasn't worried, I was just making sure I didn't twist it a certain way or grab an item a certain way) the tingling in my leg stopped! On the 3'rd day I thought, "Oh wait! The leg tingling is gone!" My arm is no longer sore, but since I got out of the leg obsession the tingle is still gone)
Also from November of 2004 to December of 2005 I had a bad pressure pain in the pit of my stomach - all day long practically, and every day. I finally went to a gastro doctor and had an endoscopy. From the moment they told me nothing was wrong, that pain went away, never returned.
