Hello I was reading your post about how your child has a pws stain on her right arm.

I also have a pws on all of my right arm and fingers too. When I was 10 years old I went for laser surgery for around 5 years however it did not work for me. The only thing that I have noticed is that when my hands get cold my fingers start to swell slightly and the hand becomes tight but there is no evidence that this was due to the laser.
I have also searched for other treatments and have had no luck so far
