let me say welcome to you!
So you do not know where you got it - like me. I know of tickbites I got here (garden) and some I got abroad. I was in the very same situation like you, means: is the result of the testing representative to bb in general or not (the sensu stricto vs. sensu lato thing). I was told that the outer surface proteines (Ospa) are representative for sensu lato. I dont know if that is really tru or just whishful thinking of the labs.They did a westernblot too to check the Elisa results because I could have brought a lot of stuff home which they said could possiblly interfere the Elisa and cause a positive result.
Another story is that nothing is impossible: I know of somebody who stayed in Central America and got very sick back home; he stayed at places where there should not be Leishmania, but the got it and he got it real bad.
I think I would rule out as much other possible infections as I can with bloodtests and then go the abx route so see what happens.
I hope you get better soon! dorit
