I don't know which disk it is. It's not even marked on my CD. I might do some checking here, though, and see about getting the shot for now and then moving over to another form of treatment. I was in so much pain, I had to get by ambulance to the ER Sunday night. They had to get me out of bed and carry me downstairs all the while me telling them to straighten me out because they had me bunched up and the pain was unbearable. The meds I'm on now are great, but I can't work while using them. Later, QD.
