I had a double mastectomy a year ago and they took quite a few lymph nodes. I didn't notice any lymphedema for a year. Thanksgiving came and I ate everything wrong. My lymphedema symptoms show their ugly head. I searched the internet and found this product. I bought the machine the sleeve for the arm and hand and then I purchased the Torso sleeve. I use them in combination one after the other and it is working. I'm sure it's something I'm going to have to do for years to come but it's not a bad thing it feels pretty good. The sleeve for the arm took away my pain almost immediately. The sleeve for the Torso has some really cool things in it as well. It massages your back like little bitty fingers as it's working. I would happily recommend this to anyone. One of my fears was that because this is from out of country I would not receive it. I received everything within one week of ordering. I'm very satisfied!
