I too was told I had labs after a 3 week bout of strange sx's (VERY similar to alot of sx's posted here) in 2008. Symptoms acted up again in 2009 and I was told it was stress & low vit d. I was tested for Lyme in Nov. 2009 and mine too was negative. I had suspected Lyme though before and posted on a Lyme website.
I found an LLMD and you guessed it, I have Lyme and babesia. I only recall a deer tick in 2001, unfortunately when I was pregnant win my first child and yes, he has it too.
I am assuming my youngest has it too since she had her appt last month and we didn't get a call to cancel it if the test came back negative.
Hubby is next to get tested.
I have been on abx since January and am 90% better. The sx's my son HAD, are gone, YEA!, since he started abx over 2 months ago. (apparently kids get rid of it easier thank GOD)
I guess now I have to get myself to 100% and start my daughter on abx. BTW, my daughter has special needs and seizures so we are thinking it's all related.
Good luck too you with your tx!
