Can a port wine stain cause physical pain?
Hi. This is my first post. I'm a 33-year-old female and I have a port wine stain birthmark on my left knee. Since I was a child, my left knee would get very achy - especially with cold or damp weather. In the past 10 years or so, I've had persistent achiness in my left knee and leg. My left leg "falls asleep" easily and, in the past few years, I've noticed my left foot does the same. Could any of this discomfort be caused by my port wine stain birthmark? Thanks for your input.
