I am a Pole. Healing back pain is not translated in Polish, but MBP is translated (in 2005), the Polish title is "Recepta na zdrowie, lecząc ciało lecząc ból". It is available everywhere.
I cannot read any Polish, so when my friend comes over, we will order. Thanks again. If we have any problems, I will let you know. Now I just hope she can believe! I am one of the people who has been fine for 10 years now, after being in terrible pain for years. So I know it works! Still, people never seem to believe me!
