About 4 years ago I developed morphea. A year later my liver enzymes were elevated and the doc ordered a test for hepatitis C. It was positive. I had no risk factors for the hepatitis, no transfusions, no IV drugs ever in my history. It's a long story, but ultimately I treated for the hep c. That treatment aggravated the morphea, but I licked the hepatitis and am now morphea-free. I think everybody with a weird autoimmune disease should ask for a hepatitis C test - in fact everybody should.
Tick bite associated morpheas are known,and antiiotic doxycycline is supposed to help in clearing.
