Clear recommendation for back pain

If you suffer from chronic back pain, this mat is the solution. Every day a few minutes (ideally, 20 min) lie still on. After the back is well supplied with blood and the pain seem gone. The effect is immediate.
Although the pain will come back but be zusehens less with regular use.
In the beginning I recommend a thin T-shirt, because you have to get used to the sharp needles. Please an old T-shirt that can be punctured in advance. Later go on bare skin, which is also the most effective.
