My massage therapist mentioned it to me, although, the other symptoms that would normally accompany it I do not have. I have always been a very fast healer, I do not bruise easily, and as far as I know, my skin doesn't stretch more than anyone else's would. I have been Vitamin D deficient for somewhere around 4 years now, even taking something like 10,000iu daily isn't raising it quickly, but it has been steadily raising it these last few months with the change up in dosing. The skin doesn't feel any different to any of the doctors I have seen so far, as well as the the skin quickly retightening when letting go (which can also be used to test severe dehydration I understand). I can always ask them about it, but, as there is only a few forms that can be tested for, it would be a hard diagnosis.
