Bio-freeze, capsacian or ibuprofen?

I am having real success from reading The Divided Mind, and doing the homework each day, usually for a bit in the morning and a bit in the evening. I have noticed that in the morning when I first wake up, I can be a little stiff and the pain is mostly in my shoulders, when it was originally in my low back. My question is, while I'm confident that doing the work and reading Dr. Sarno's work and success stories is already curing me of this, will using something like bio-freeze, or capsacian or taking ibuprofen in the morning when I wake up with stiffness or pain slow down complete recovery? I've seen interviews of Dr. Sarno briefly talk about it, but was hoping someone could give me more information about it.
