As a healthcare professional, I recommend this product!
As an acupuncturist, I've dealt with a lot of patients who have "knots" in their back muscles.  This is a great, simple way for someone to work those knots out themselves.  I'm not saying it will fully replace a massage or acupuncture treatment if you have severe chronic pain, but it's a great way to lessen the amount of treatments you may need and works great for those with just a few sore spots.  I bought 3 of these as gifts last Christmas for family members.  Perhaps ordering yourself a trigger point chart would help as well.
