thanks - the dermatologist she saw today also prescribed Methotrexate so I guess she will be taking it. I have asked her to query how long they think she will take it for. No-one seems to know much about localised scleroderma. Prevalence is about 3 in 100,000 people. There seems to be no way of finding out whether it is active or not, or whether it has gone away.... So effectively she is taking Methotrexate "just in case", but if she doesn't and it is still active, then the consequences could be worse. Hopefully she won't have to take it as long as you did.
