I was having trouble with low back pain and joint pain. I saw a few Orthopedic Surgeons who was constantly injecting cortisone into my joints, which had more side effects than helping with the pain! I also saw a Foot and Ankle Specialist who told me after several office visits not to return, because my blood work, MRI scan and X-Ray results came back normal and he’s not sure what to treat me for. Since I have begun taking the Joint & Muscle supplement which I purchased from MD Logic, I have had significantly less pain in my hips and knees. I am now able to stand for longer periods of time. Also, I was having painful foot and leg cramps most of the day and night. I do not know if there is something in this product that also reduces leg cramps, but I have not had leg cramps since after the first week on the supplement. Starting to feel like my old self again is an Absolutely Amazing feelings. I've experienced no stomach upsets either! I highly recommend this product.
