Don't overlook BLAST. I was given no post procedure instructions the first time I had an scs trial. I did everything I wasn't supposed to. I did them very gently but never means NEVER. My trial failed big time. My guess is the leads migrated due to my movements. I will spare you the details. Best wishes. My scs trial is scheduled for Aug 7th. Deep cleansing breath. It only took me 15 years to work up the nerve.....and to become desperate enough, to try again. Different doc and I am a whole lot smarter this time around.
