I have been using the Liquid Manna for only a short time and have experienced a satisfactory result. I have had pain in my shoulder due to a fall and pain in my neck due to whiplash for the past few years. Although the pain is not yet completely gone, I feel that the pain in my shoulder is reduced at least 60% and the pain in my neck at least 85%. Also, the water has helped with floaters in my eye. Looking forward to more of the same.
