First of all, please tell your friend not to panic, the added stress won't help her at all. Another thing is she could have a co-infection.
I would like to recommend that she do some reading on this site:
www.drjoneskids.com/ It's a site from Dr. Charles Ray Jones, who is known for his successful treatment of children with Tick-borne infections, and has a section on Pregnancy and Lyme.
Also, why not suggest that she join us! Even if she says she doesn't want to join, she can always do some reading on this site!!
