For the last 10 years i have been suffering from this disease

I'm 17 and the disease keeps spreading. I have white spots all over my leg and upper arms. I've been to the derm several times but she keeps telling me that there is no treatment and i just have to live with it

But i've been searching on the web and i found a couple of sites [url]http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_u ids=2229495&dopt=Abstract[/url]

there are more just tick in guttate hypomelanosis cryotherapy on ******
now my derm had tried it once but she had no experience with the treatment. the spot became bigger then it was before but i dont know maybe she froze it to long or something she said she never heard of the treatment
have anyone heard of this treatment? or is there another treatment that works please let me know
