Have been diagnosed to be needing two knee replacements. Fell in September 2019. Due to COVID, only Saw my surgeon this week. Because of health issues , replacements urgently needed, but possibly not a good outcome if go ahead. I bought two of the knee sleeve,have used daily and have found these to give me some 60 minutes of free from pain. They are so easy to use, make me sit and take a break , thus gives me a 2nd wind to start off again. Would highly recommend. Also bought 2 of the larger pain pads , as hips area thrown out from knee injury. These are so good and effective, having a larger surface to work with xx Can’t believe I didn’t find you sooner !
