I have heard of people doing their own treatment, with the help of someone. Basically you have to learn how to puncture the vein and that's about as hard as it gets. My doctor in Trento has a 30 year old German machine, so I don't know how much new machines cost, I will contact my doctor in Milan and ask him how much he paid for his. I think in Italy, and it might be the same for you in Germany the government can help you out when it's medically necessary. As far as my progress, yes I am truly amazed, and my case is one of the severe ones. $ 25 a treatment sounds great, I hope you try it and it goes really well for you.
