I was diagnosed with limited curtaneous systemic scleroderma and secondary reynauds 2 years ago. My consultant advised me to stay out of the sun but didn't say why. I would like to know why, if anyone can educate me I would be very grateful. I am under a rhuematologist but don't think he is a specialist in scleroderma as his answers are very vague. I am taking ramipril, omoprazle (probably the incorrect spelling), viagra instead of the ilprost infusion, vitamin D.
