May I ask which tests you were positive on?Maybe so, but an IV antibiotic which is often used for Lyme and gets into the CNS was very helpful for me. I had a textbook Hermxheimer reaction, which should only happen in response to very specific types of bacteria - only spirochetes which produce toxins as they die off.
My personal experience strongly suggests a long-term Lyme infection, and it is this far strongly suggesting that 6 weeks of IV antibiotics has a big impact on Lyme and ME symptoms. For the past 5 days I have been incredibly active by my usual standards. I got a little sore the first couple days, but nothing resembling a crash, and now I'm able to do many household chores every day, without struggling at all - chores I haven't been able to safely do for a couple years.
Also, did you try oral antibiotics (and if so, which ones and for how long)? And what was the reason you went on IV abx (as opposed to oral)?
Thanks. I am asking because I am positive for Lyme by PCR but around 9 months of oral abx has produced not effect in me. Yours is the first case I've found of an improvement!
