Hi IH8Ticks - nausea is in the bart- symptom list I was given; also listed are: swollen lymph nodes (said this is very common), muscle pain, abdominal pain, exantheme, milt may be involved, possibly fever, headaches, CNS lesions (as complication). I do not think that common stretch marks are usually red, the ones I saw in my life had the colour of the surrounding skin.
My friend got it from her cat after being bitten and scratched (infection rate of cats here are 45% !!!); the bite got covered with somewhat of a dark papule and she got swollen lymph nodes and fever, never developed those stretch marks but got milt problems and severe headaches. (I run when I see the cat)
This all is so much a detective`s work... As meds "first choice" they recommend macrolides or as alternative doxy or rifampicin - but I stay in Europe.
Thats all I can offer but I think you will get more answers from the others pretty soon. Wish you a quick recovery!! dorit
