Scleroderma is a very personal disease, meaning each person has very different issue than the next. So there really isn't one main symptom that is the worst in general. For myself the worst symptoms would have to be my skin and how tight it has become. It causes me to get horrible ulcerated sores on my hand and feet. And my lung function which has been steadily getting worse. I have pulmonary fibrosis and it's becoming harder and harder for me to breath on my own.
