I’ve had surgery with a torn meniscus on both knees. I have had shots, taken pills and used creams , but after awhile everything stops working. I have used Cryofreeze for over two years every night for the reoccurring nighttime knee pain. I had a knee replacement on my left knee six months ago, and still use Cryofreeze on both knees at night. Even on the knee with the replacement… different type of pain… but I still get relief from Cryofreeze. Not with joint pain this time, but with the muscle pain. I would highly recommend this roll on, it dries fast, and last a long time. I have it on auto reorder with a nice discount and free shipping.
