I'm glad you've found us and that you now know how much it is you don't know. This is one disease where self-education is absolutely vital to know even what questions to ask your doctor.
Sometimes they just need to mention that amputation is a potential "treatment" on the horizon. They are especially likely to bring up that topic if you are doing anything at all that could be making your illness worse, such as smoking, alcohol use, caffeine, street drugs, not avoiding cold and keeping warm at all times, not properly managing blood sugar, high stress, medications with vasoconstricting side effects, or not following all of their instructions. I've known people who have had several amputations before making necessary lifestyle changes, and then again, some never do.
If by any chance you are not following *all* of your doctors instructions to the absolute max, then amputation might be a very high likelihood, especially when combined with any type of scleroderma. Our rule of thumb is that whenever any of us are inclined to be noncompliant or self-destructive, it is a good idea for us to start (or continue) counseling to learn tools and techniques for enabling self-love and establishing and reinforcing new and better habits.
Most unfortunately, with some illnesses, including scleroderma, it is possible to do absolutely everything right, and still suffer amputations. Sometimes people get discouraged by that idea, and take it as meaning they shouldn't even try. But of course, surrounding yourself with great support and encouragement to be as healthy as possible under the circumstances, and getting the best medical advice possible, can make a world of difference and at the very least keep unavoidable damage to a minimum.
