These infections are good at mimicking autoimmune issues. I would encourage you to take a look at the connection between scleroderma and Lyme disease. Here is one article showing the connection:
/www.ncbi.nlm.nih.gov/pubmed/15649200 and there are quite a few personal stories online about
scleroderma and Lyme.
Hopefully some that have had this diagnosis will be along soon to post about
their experiences.
