I have been under doctor's care for old back injury, which for some reason, all the sudden returned a month ago. I had a great deal of pain that started from the sciatic around to the hip and into my groin. I had to leave work for a little over 2 weeks and now I am back to work for 3 half days a week. While picking up a presecription at my pharmacy, Cortez Drugs, I saw the sample packets that I purchased for a minimal price to "try" the capsules to see if they work for me before purchasing a whole bottle. I was astounded by the relief of just one pill. The pain I was dealing with was so excrutiating that I could not sit, lay or stand in one position for more than 15 minutes at a time. Ice on and off every 2 hours. I was reluctant on taking too many over-the-counter pain relief due to side affects. When I took the capsules I received a reduction in pain and spasm within 15 - 20 minutes. What a relief! So I will be heading to my pharmacy to purchase a whole bottle. Thank you very much, for making the packets to try first. I would have never spent the money, just to try a whole bottle. Great product and really works well for me!
