Hi I'm 40, female and healthy. I've had this problem since i can remember. It's worse in the cold (winter) but has otherwise not affected my life. Hope all goes well for your son!
hi i have what sounds just like what your son has. I have had it for about 4 years though and my hands are almost always discoloured unless i hold them above my head for a bit.
Please can you let me know what the doc said to your son :)
