"my friend, a registered nurse, recommended this product.  like a lot of women, i have sporadic pain in my shoulder and neck area.  whether this is the result of stress and/or carrying a heavy purse, i don&#039;t know.  anyhow....i tried the patch and within 90 minutes my pain was gone!  i have since recommended this product to other women at work with the same issues and they also had good results."
