Suggest Treatment For Morphea

48years, Female, Asian Wt 79 kg Ht 161 cm. Dear Doc, I did biopsy 3 years back for one spot on my stomach and it said Morphea, no medications only skin peeling ointment was given. Now my full stomach is covered with it and a few in the back .New ones are appearing on my arms but are a little different with more wrinkled skin. When will it be over, will it cause any disability, is there any medication? Please advice
