I had an attack of sciatica in January of this year that was the worst I've ever experienced, 6 months later I still have numbness and my other leg has become very pain full with muscle strain with over compensating. Anyhow this has affected me greatly as I've not been able to get out walking like I used to and going up and down stairs is hard going. My legs were aching all the time which would also affect my sleeping. I received this machine yesterday and couldn't wait to use , even if it provide some temporary relief it would be worth it. I spent a relaxing half hour having my legs squeezed and massaged and I could feel an instant difference. I had a great afternoon managed to walk with very little discomfort and get up 4 flights of stairs and down them again without struggle.i used it again before bed and had the best night's sleep I've had in over 6 months. I am delighted I bought it for so many reasons, it's easy to use, set up can be taken with you if your travelling and the benefits of reducing pain and increasing circulation is already showing me benefits. It literally takes a minute to set up, choose your setting and the machine does the rest...you will be relaxing before you know it.
