I have a torn meniscus (diagnosed by MRI) that has been debilitating for 6 months. I tried physio, NSAIDs, RICE, and restricted activity but nothing was helping. The sharp, stabbing pain was ruining my day to day life. I started using this Revitive tool last week - 2 times daily for 5 min at full strength. Within 2 days I noticed a reduction in pain. Now, 5 days later, I have significant pain reduction, am walking without limping and am reducing my NSAIDs gradually. My husband is now using this for his pinched ulnar nerve.
