Hi, Another question for you all.

Do you have to have Raynaud's before you start getting Ulcers on your fingers?

Hi Celia! You ask a very good question. I think that in order for finger ulcers to form there should be some lack of oxygenation to the skin, such as Raynauds. I've never heard of anyone getting finger ulcers without Raynauds. But then again, I'm no Dr.


Good luck,

That is a good question. I did a little research on our digital ulcers page and found this statement in an article on Blood Viscosity and Raynaud's.


"over 90 percent of scleroderma patients develop what is called Raynaud's phenomenon characterized by blue and red discoloration of the hands and often leading to painful digital (finger) ulcers."


The main finding is that they both indicate vascular involvement with scleroderma. As Claudia mentioned, the ulcers are due to lack of oxygenation to the skin. This can be caused by restricted blood flow due to the shrinking or damaged capillaries and high blood viscosity. Keep those hands warm!!! The best way to do that is to keep the whole body warm.
