Is it just me, or does this seem to be a case of two steps forward, one step back? I'm sorry you have scleroderma (of whatever type) but I'm also glad that you've achieved a diagnosis.
Judy and Jo are spot on, as usual, in that the big question now is, exactly what type of scleroderma do you have? There are many different types and they vary drastically in how they can affect us, and you need to know what type in order to get the best evaluation and treatment.
I'm pretty sure I see a Scleroderma Expert in your future. Odds are you will need to get a referral to one because usually the local doctors have exhausted the limits of their knowledge on the subject by merely trying to pronounce the word.
If you doctor didn't specify which type (which happens to be extremely common), you will probably be able to figure it out yourself from the link above. I am thinking you might have localized (morphea/linear), since that is the most popular type to be diagnosed via a skin biopsy; and of those, most likely morphea, because linear is so unique that it is usually diagnosed just by looking at it.
Morphea appears in red or purplish or brownish sort of skin patches that often have a lighter center, such as pink or light purple or beige. Most people just get one or two spots that are fairly mild and may even start to clear up on their own in three to five years. But some people develop more spots, or larger, deeper or more prominent spots (like over a joint or on the face.) Currently UVA1 phototherapy seems to be the first-line treatment they recommend in most cases, and it shows a very good success rate.
But, I've gone on and on, with all sorts of assumptions, and you know what "assume" means! Did your doctor share anything more with you, like the type of scleroderma, and your possible treatment options?
