My daughter bought this for my husband for Christmas. He has a multitude of aches and pains -- shot rotator cuff, torn ligaments in one arm, back pain from a rib injury many years ago, a painful lump on the side of his foot. He was nothing short of amazed at the effectiveness of Saje Pain Release -- worked within seconds to relieve the pain. And he was pleased that it did not involve medication taken internally. He even put it on his cheek to see if it would relieve the pain he had following a difficult oral surgery he had just had, and was able to sleep on that side for the first time in a week!! The only reason I gave it only 4 stars is because he's only had it a couple of weeks so not sure about the longevity.
